The standardization of terminology for researchers in female pelvic floor disorders.

The lack of standardized terminology in pelvic floor disorders (pelvic organ prolapse, urinary incontinence, and fecal incontinence) is a major obstacle to performing and interpreting research. The National Institutes of Health convened the Terminology Workshop for Researchers in Female Pelvic Floor Disorders to: (1) agree on standard terms for defining conditions and outcomes; (2) make recommendations for minimum data collection for research; and (3) identify high priority issues for future research. Pelvic organ prolapse was defined by physical examination staging using the International Continence Society system. Stress urinary incontinence was defined by symptoms and testing; 'cure' was defined as no stress incontinence symptoms, negative testing, and no new problems due to intervention. Overactive bladder was defined as urinary frequency and urgency, with and without urge incontinence. Detrusor instability was defined by cystometry. For all urinary symptoms, defining 'improvement' after intervention was identified as a high priority. For fecal incontinence, more research is needed before recommendations can be made. A standard terminology for research on pelvic floor disorders is presented and areas of high priority for future research are identified.

Neuroanatomy of the female continence complex: clinical implications.

OBJECTIVES: Improved understanding of pelvic neuroanatomy in women has led to modified surgical approaches and additional considerations in pelvic surgery. The innervation of the external urinary sphincter and urethra is not well defined in women, and, as such, the continence complex is not well understood. METHODS: Fourteen pelvic sections from seven fresh female cadavers were dissected to investigate the neuroanatomy of the female continence complex. RESULTS: Neuroanatomic dissections of the continence mechanism revealed that branches of the pelvic nerve travel beneath the fascia of the levator ani muscle and approach the urinary sphincter in near midline position, posterolateral to the rectum. This pelvic nerve branch passes laterally around the vagina and rectum to enter the sphincter musculature at the 5-o'clock and 7-o'clock positions. The pudendal nerve, traveling in the pudendal canal, gives an intrapelvic branch that courses to the urinary sphincter. At the level of the proximal urinary sphincter, it joins the pelvic nerve branch to the urinary sphincter. CONCLUSIONS: These neuroanatomic dissections provide a basis for surgical modifications that may address a variety of concerns regarding urinary continence in female surgical patients. With improved understanding of the female continence complex, we may now have a more precise anatomic explanation for the high failure rates associated with transvaginal urethral suspension procedures. Additionally, awareness and preservation of the continence nerves during cystectomy may allow for greater use of orthotopic bladder replacement in women.

Inducible nitric oxide synthase in the bladder of spinal cord injured patients with a chronic indwelling urinary catheter.

PURPOSE: Spinal cord injured patients are at increased risk for bladder carcinoma. Nitric oxide production in areas of chronic inflammation may provide a stimulus for carcinogenesis by serving as a source of nitrosating agents that generate potentially carcinogenic nitrosamines from secondary amines normally present in urine. MATERIALS AND METHODS: To determine whether inducible nitric oxide synthase is expressed as a catalyst for sustained nitric oxide production by cellular elements in chronically inflamed bladder mucosa immunohistochemical studies were performed on mucosal biopsies obtained from 37 adults with spinal cord injury. All participants had required a chronic indwelling urethral or suprapubic catheter for greater than 8 years. RESULTS: Histopathological studies revealed active inflammatory infiltrates in all 37 biopsy specimens, squamous metaplasia in 20, epithelial dysplasia in 3 and carcinoma in 1. Inducible nitric oxide synthase was detected in inflammatory cells localized to the lamina propria. Inducible nitric oxide synthase positive cells were identified as macrophages using monoclonal antibodies to macrophage antigen. There was no inducible nitric oxide synthase expression in the urothelial cell layers. Immunostaining for inducible nitric oxide synthase was not detected in bladder mucosal biopsy specimens obtained from cadaveric organ donors. CONCLUSIONS: Inducible nitric oxide synthase is expressed in inflammatory macrophages in areas of chronic inflammation in the bladder mucosa of spinal cord injured patients with a chronic indwelling bladder catheter. The expression of inducible nitric oxide synthase may potentially lead to the sustained production of nitric oxide and its oxidative products, the nitrosation of urinary amines and the formation of potentially carcinogenic nitrosamines in the bladder.

Delivery of injectable agents for treatment of stress urinary incontinence in women: evolving techniques.

PURPOSE: Periurethral bulking agents continue to be used as a minimally invasive alternative for management of stress urinary incontinence in men and women. Agents and delivery techniques will be evaluated and compared. MATERIALS AND METHODS: The only agents currently approved by the United States Food and Drug Administration (FDA) include glutaraldehyde cross-linked collagen, autologous fat, and carbon bead/carrier gel technology. Several other agents are undergoing FDA trial evaluation. These agents differ in material characteristics (particle size, viscosity) that, in some cases, produce different immediate and delayed tissue responses or reactions. RESULTS: Initial subjective cure rates with collagen are acceptable, but the majority of women require reinjection. The risk of allergic phenomena complicates collagen use. Carbon-based material appears to parallel collagen in durability, with the significant advantage of a nonimmunogenic response within host tissues. Autologous fat injection achieves early results similar to those with collagen, but is limited by resorption and fibrous replacement as well as local discomfort associated with harvesting procedures. Experience with newer agents is limited. Patient characteristics also influence response to injectable agents. CONCLUSIONS: Injectable agent materials and delivery techniques continue to evolve. The optimal material is yet to be defined.

Injectable agents in the treatment of stress urinary incontinence in women: where are we now?

Periurethral bulking agents have been used for decades. The only currently available agents (in the United States) include glutaraldehyde cross-linked collagen, autologous fat, and carbon bead technology. Initial subjective cure rates with collagen are acceptable, but with the majority of women requiring reinjection. The risk of allergic phenomena complicates collagen use. Autologous fat injection is initially effective in >50% of women, but resorption and fibrous replacement hamper the stability of the transplanted graft. Polytetrafluoroethylene and silicone are not currently approved by the US Food and Drug Administration because of particle migration. Materials in development include biologic agents such as allogeneic human collagen and autologous cartilage. Developmental synthetic agents include microballoon technology, hyaluronic acid with or without microsphere technology, hydroxylapatite, and a variety of polymeric technologies. Patient selection and material characteristics influence the optimal choice for injectable agent.

Advancements in pharmacologic management of the overactive bladder.

Continued developments in the understanding of lower urinary tract function have led to improvements in the pharmacologic manipulation of bladder dysfunction. Drug delivery changes have produced drugs that provide better efficacy and tolerability, thus improving patient compliance. Improvements in drug delivery systems have altered drug bioavailability and pharmacokinetics. Active current investigation in new agents and delivery systems for intravesical delivery has yielded intriguing early results that may substantially add to the armamentarium for the management of the overactive bladder (urgency, frequency, urge incontinence). New developments in the understanding of the neuropharmacology of the bladder, peripheral pelvic nerves, and sacral cord may provide agents with entirely new drug effects, either as primary agents or agents to be used in combination with currently available drugs. We herein review newer agents and drug delivery systems.

Clinical significance of detrusor sphincter dyssynergia type in patients with post-traumatic spinal cord injury.

OBJECTIVES: To investigate the significance of categorizing detrusor sphincter dyssynergia (DSD) by type in patients with chronic spinal cord injury. METHODS: A retrospective review of the charts, video-urodynamic studies, and upper tract radiographic studies of 269 patients with post-traumatic, suprasacral spinal cord injuries was performed. The patients were categorized according to the DSD type (intermittent or continuous), level and completeness of injury, intravesical pressure at leak, upper tract complications, and interval since injury. RESULTS: Of the 269 patients, 20 (7.4%), 216 (80.3%), and 33 (12.3%) had no DSD, intermittent DSD, and continuous DSD, respectively. No significant association between the specific level of injury and the DSD type was found (P = 0.71). The presence of DSD was associated with complete injuries, elevated intravesical pressures, and upper tract complications (P <0.01); these associations were more prominent with continuous DSD than with intermittent DSD. The proportion of patients with no DSD, intermittent DSD, and continuous DSD was unchanged during the chronic follow-up period. CONCLUSIONS: The clinical significance of DSD type is not crucial, since patients with both intermittent and continuous DSD require urodynamic surveillance and expedient treatment to minimize urologic complications. However, the presence of continuous DSD is one of several factors that may require earlier urodynamic follow-up.

Neuroanatomy of the pelvis: implications for colonic and rectal resection.

PURPOSE: Urinary dysfunction remains a common complication of radical pelvic surgery, particularly after abdominoperineal resection. In treating rectal carcinoma, the extent of primary resection and lymphadenectomy are major determinants in the degree of postoperative urologic morbidity. METHODS: Twelve male and eight female hemipelves from fresh cadavers were dissected with reference to the neuroanatomy of the lower genitourinary tract. These cadavers were dissected within twelve hours of thaw from frozen state. The cadavers were hemisected at the level of the sacral promontory for better exposure of neural trunks and vascular structures leading into the pelvis. These structures were followed down sequentially into the true pelvis, using magnified dissection under operating microscope or loupe dissection or both. RESULTS: Coordinated lower urinary tract function relies on both autonomic and somatic nerve activity. Emanating from the inferior hypogastric plexus, the pelvic nerve supplies sympathetic and parasympathetic innervation to the pelvic viscera. The course of the pelvic nerve is as follows: 1) from the inferior hypogastric plexus, it has multiple branches forming a web-like complex within the endopelvic fascial sleeve, some of which innervate the bladder detrusor; 2) a main branch traveling inferolateral to the rectum remains deep to the fascia of the levator ani muscle and courses to the external urinary sphincter; 3) at the level of the prostatic apex (or bladder neck in females), this pelvic nerve branch sends direct branches to the urinary sphincter. The pudendal nerve traverses the pelvis in the pudendal canal, and before leaving the pelvis to enter the perineum, it gives an intrapelvic branch that courses alongside the ischium to enter the external urinary sphincter. In the ischiorectal fossa, terminal branches of the pudendal nerve (i. e., perineal nerve) can be seen inserting into the urinary sphincter. CONCLUSIONS: Urinary retention and urinary incontinence represent two distinct urologic complications after abdominoperineal resection. Injury to detrusor branches of the pelvic nerve can cause detrusor denervation and urinary retention. In addition, injury to intrapelvic branches of the pelvic and pudendal nerves to the urinary sphincter can result in intrinsic sphincter deficiency and urinary incontinence. A better understanding of the neuroanatomy of the lower genitourinary tract can give a physiologic basis for clinical findings of postoperative voiding dysfunction and may help the surgeon refine surgical technique by more precisely determining resection limits to minimize urologic complications.

Association of level of injury and bladder behavior in patients with post-traumatic spinal cord injury.

OBJECTIVES: The expected urodynamic findings of patients with suprasacral and sacral spinal cord injury have previously been reported. However, the associations between the radiographically determined level or levels of injury and urodynamic findings are ill defined. This study investigated these relationships, specifically the bladder behavior of patients with post-traumatic spinal cord injury with combined suprasacral and sacral injuries. METHODS: A retrospective review of the patient records, spinal imaging studies, and video-urodynamic studies of 316 patients with post-traumatic spinal cord injury was performed. Of these patients, 243 had complete spinal computed tomography or magnetic resonance imaging studies and constitute the study population. Patients were categorized by the radiographically determined level or levels of injury, clinical neurologic level and completeness of injury, and urodynamic findings. RESULTS: Of the 196 patients with suprasacral injuries, 186 (94.9%) demonstrated hyperreflexia and/or detrusor sphincter dyssynergia, 82 (41.8%) had low bladder compliance (less than 12.5 mL/cm H(2)O), and 79 (40.3%) had high detrusor leak point pressures (greater than 40 cm H(2)O). Of the 14 patients with sacral injuries, 12 (85.7%) manifested areflexia, 11 (78.6%) had low compliance, and 12 (85.7%) had high leak point pressures. Of the 33 patients with combined suprasacral and sacral injuries, urodynamic studies showed 23 with hyperreflexia and/or detrusor sphincter dyssynergia (67.7%), 9 with areflexia (27.3%), 19 (57.6%) with low compliance, and 20 (60.6%) with high leak point pressures. CONCLUSIONS: In patients with a single level of spinal cord injury, this study revealed a significant association between the level of injury and the type of voiding dysfunction. Patients with combined suprasacral and sacral injuries, as identified with precise spinal imaging techniques, had relatively unpredictable urodynamic findings. Management of the urinary tract in patients with spinal cord injury must be based on urodynamic findings rather than inferences from the neurologic evaluation.

Effect of bladder management on urological complications in spinal cord injured patients.

PURPOSE: The optimal method of bladder management in spinal cord injured patients remains controversial. We investigated the association of type of bladder management with urological complications in these patients. MATERIALS AND METHODS: We retrospectively reviewed the medical records, upper tract imaging and video urodynamics of 316 posttraumatic spinal cord injured patients. Mean followup plus or minus standard deviation since injury was 18.3+/-12.4 years. Patients were categorized according to bladder management method, including chronic urethral catheterization, clean intermittent catheterization, spontaneous voiding and suprapubic catheterization in 114, 92, 74 and 36, respectively. No significant differences in patient age at injury, followup interval, or level, completeness or mechanism of injury were noted among bladder management method groups. Infection, stone disease, urethral complications and radiographic abnormalities were recorded. RESULTS: Of the 398 complications recorded 236 developed in 61 (53.5%) patients on chronic urethral catheterization, 57 in 25 (27.2%) on clean intermittent catheterization, 57 in 24 (32.4%) who voided spontaneously and 48 in 16 (44.4%) on suprapubic catheterization. The intermittent catheterization group had statistically significant lower complication rates compared with the urethral catheterization group and no significantly higher complication rates relative to all other management methods for each type of complication studied. The percent of patients with complications was greater in the chronic urethral catheterization group only 5 years after injury, while the percent in all other management groups remained similar up to 15 years after injury. CONCLUSIONS: Clean intermittent catheterization is the safest bladder management method for spinal cord injured patients in terms of urological complications. Inappropriate selection of a bladder management method not only adversely affects patient quality of life, but also has a significant detrimental impact on the economic status of the health care system.

Differences in bladder compliance with time and associations of bladder management with compliance in spinal cord injured patients.

PURPOSE: Controversy continues on the optimal method of bladder management in spinal cord injured patients. We investigated the effects of bladder management on bladder compliance and changes in compliance with time. MATERIALS AND METHODS: We retrospectively reviewed the charts, and video urodynamic and upper tract radiographic studies of 316 patients with spinal cord injury. Patients were categorized according to interval since injury and bladder management method, including clean intermittent catheterization, spontaneous voiding and chronic Foley catheterization. Those with upper tract complications were compared with asymptomatic controls at the bladder compliance threshold values of 10.0, 12.5, 15.0 and 20.0 cc/cm. water. RESULTS: No significant differences were noted among bladder management method groups for followup, level, completeness or mechanism of injury. A bladder compliance threshold of 12.5 cc/cm. water was selected for the remaining comparisons based on the frequency of complications compared with asymptomatic controls. Patients using intermittent catheterization had a significantly higher incidence of normal compliance than the Foley management group for suprasacral, complete and incomplete injury (p<0.01). Normal bladder compliance was more common in patients with suprasacral than sacral and incomplete than complete spinal cord injury for each bladder management type. Logistic regression analysis of compliance versus bladder management and age of injury (interval since injury) revealed that intermittent catheterization and spontaneous voiding were associated more with normal compliance than Foley catheterization (RR = 9.2, 5.4 and 1.0, respectively). Combined data showed that each successively older age of injury cohort was at 23% greater risk for loss of normal compliance than the preceding cohort. Low compliance was statistically associated with vesicoureteral reflux, radiographic upper tract abnormality, pyelonephritis and upper tract stones (p<0.01, <0.01, 0.04 and <0.01, respectively). CONCLUSIONS: Clean intermittent catheterization protects bladder compliance in spinal cord injured patients regardless of the level or completeness of injury and helps to prevent low compliance with time. Also, in the population studied low compliance was associated with upper tract complications. Therefore, clean intermittent catheterization is the superior method for preserving bladder compliance and preventing the upper tract complications associated with low compliance.

Influences on renal function in chronic spinal cord injured patients.

PURPOSE: The optimal method of bladder management in the spinal cord injured population remains controversial. We determined the significance of bladder management and other factors on renal function in this population. MATERIALS AND METHODS: We retrospectively reviewed the medical records and upper tract imaging studies of 308 patients with a mean followup of 18.7 years since injury. Renal function was assessed by serum creatinine, creatinine clearance and proteinuria measurement, and by upper tract abnormalities on renal ultrasound and nuclear medicine renal scan. Independent variables evaluated for an influence on renal function included patient age, interval since injury, injury level and completeness, vesicoureteral reflux, history of diabetes mellitus and bladder management method. RESULTS: Mean serum creatinine plus or minus standard deviation in patients on chronic Foley catheterization, clean intermittent catheterization and spontaneous voiding was 1.08 +/- 0.99, 0.84 +/- 0.23 and 0.97 +/- 0.45 mg./dl. (analysis of variance p = 0.05, Student's t test p = 0.10), and mean creatinine clearance was 91.1 +/- 46.5, 113.4 +/- 39.8 and 115 +/- 49 ml. per minute, respectively (analysis of variance and Student's t test p <0.01), respectively. Proteinuria was present in 19 patients (6.2%) in the Foley catheterization, 3 (1%) in the clean intermittent catheterization and 4 (1.3%) in the spontaneous voiding group (chi-square test p <0.01), while there were upper tract abnormalities in 56 (18.2%), 20 (6.5%) and 24 (7.8%) patients, respectively (chi-square test p <0.01). Multiple regression analyses revealed no significant predictors of serum creatinine, although older patient age and Foley catheterization significantly predicted low creatinine clearance. Additional logistic regression analyses showed that Foley catheterization was associated with proteinuria and vesicoureteral reflux was associated with upper tract abnormalities. CONCLUSIONS: While renal function may be preserved by all forms of bladder management, chronic indwelling catheters may contribute to renal deterioration.

Female voiding dysfunction and movement disorders.

Voiding dysfunction associated with Parkinson's disease has been well described in male patients. Few studies detail voiding dysfunction in female Parkinson patients. Apparent differences between patients with Parkinson's subtypes have also not been sufficiently defined. The majority of female Parkinson patients who have urinary symptoms (>70%) will manifest symptomatic urgency with or without urge incontinence. The remaining patients will have mixed irritative and obstructive or purely obstructive symptoms. Urodynamic evaluation demonstrates detrusor hyperreflexia in 70%-80% of female patients. However, women with Parkinson-related syndromes demonstrate detrusor hypocontractility or areflexia in 20%-30% of cases. Electromyography reveals sphincteric dysfunction (pseudodyssynergia, bradykinesia) in 30%-50% of female Parkinson patients. Also, in patients with Parkinson-related syndromes a high prevalence of peripheral denervation can be documented on electromyographic study of the pelvic floor. Voiding dysfunction associated with Parkinson's disease in female patients is complex and not always congruent with symptoms. Urodynamic evaluation is crucial to fully elucidate lower urinary tract dysfunction in female patients with Parkinson's and Parkinson-related disorders.

Bladder histological changes associated with chronic indwelling urinary catheter.

PURPOSE: Chronic urinary catheters induce histological changes in the bladder with time. The exact etiology of these changes is postulated to arise from inflammation and local tissue response. We elucidate the incidence of nonmalignant histological change in bladder biopsies of patients with chronic indwelling urinary catheters. MATERIALS AND METHODS: During 7 years 208 spinal cord injured patients underwent bladder biopsies as part of a surveillance program for vesical malignancy. All patients had chronic (more than 8.5 years) indwelling urethral or suprapubic catheters as definitive management for neurogenic voiding dysfunction. Biopsies were obtained from 4 to 6 sites within the bladder, including areas that were visually abnormal. All samples were routinely fixed with hematoxylin and eosin staining, and interpreted by an experienced pathologist. RESULTS: A total of 17 patients were identified with malignancy, including 10 with squamous cell carcinoma, 5 with transitional cell carcinoma and 2 with adenocarcinoma. Nonmalignant changes occurred in 48 patients (23%) with keratinizing squamous metaplasia or cystitis glandularis, each of which is considered a premalignant lesion. CONCLUSIONS: To our knowledge our study represents the largest group of spinal cord injured patients to undergo biopsy evaluation after chronic catheter use. A spectrum of inflammatory and proliferative pathological conditions were identified, which were predominantly inflammatory and squamous. The need to survey ongoing transitional mucosal changes in this population is underscored by the spectrum of histological abnormalities and the significant occurrence of malignant pathologies in our patients.

Preservation of putative continence nerves during radical retropubic prostatectomy leads to more rapid return of urinary continence.

OBJECTIVES: Urinary incontinence is a significant complication of radical pelvic surgery. A better understanding of the neuroanatomy of the rhabdosphincter has led to the modification of the radical retropubic prostatectomy to optimize the recovery of postoperative urinary control. METHODS: Mock radical retropubic prostatectomy was performed on fresh cadavers to determine which surgical maneuvers could injure what may be the continence nerves. To assess the clinical significance of modifying the radical retropubic prostatectomy based on these anatomic studies, a contemporary series of 60 consecutive patients who underwent radical retropubic prostatectomy with continence nerve preservation was compared with a control group of 38 consecutive patients who had a standard anatomic radical retropubic prostatectomy. RESULTS: At the level of the prostatic apex, both the pelvic and pudendal nerves gave intrapelvic branches that bilaterally coursed to the external urinary sphincter to enter at the 5 and 7 o'clock positions. The mock radical prostatectomy revealed that the nerves to the external urinary sphincter were most prone to injury when a right angle clamp was used to develop a plane between the posterior rhabdosphincter and anterior rectum and if the urethral anastomotic sutures were placed at the 5 and 7 o'clock positions. In addition, blunt dissection of the tips of the seminal vesicles injured the inferior hypogastric plexus. Modifications to preserve the continence nerves were incorporated in the anatomic radical prostatectomy. Although overall continence rates were similar for the two groups (98.3% for continence nerve-preserving radical prostatectomy versus 92. 1% for standard prostatectomy), continence nerve preservation decreased the time to achieve continence. CONCLUSIONS: During radical retropubic prostatectomy, surgical maneuvers that avoid injury to the continence nerves resulted in the more rapid return of urinary control.

Fournier's gangrene: therapeutic impact of hyperbaric oxygen.

Many controversial issues exist surrounding the disease pathogenesis and optimal management of Fournier's gangrene. In Fournier's original descriptions, the disease arose in healthy subjects without an obvious cause. Most contemporary studies, however, are able to identify definite urologic or colorectal etiologies in a majority of cases. To investigate disease presentation, treatment modalities, and overall mortality, a retrospective analysis of Fournier's gangrene from a single institution is presented. Since 1990, 26 cases of Fournier's gangrene have been diagnosed at the University of Tennessee. An evaluation of intercurrent disease revealed that 38 percent of the patients had diabetes mellitus, 35 percent manifested ethanol abuse, and 12 percent were systemically immunosuppressed. Fifteen patients (58 percent) presented with identifiable etiologies for their disease: 31 percent (8) urethral disease or trauma, 19 percent (5) colorectal disease, and 8 percent (2) penile prostheses. Management in all cases involved prompt surgical debridement with initiation of broad-spectrum antibiotics. Multiple debridements, orchiectomy, urinary diversion, and fecal diversion were performed as clinically indicated. Fourteen patients received hyperbaric oxygen as adjuvant therapy. Statistically significant results were noted with mortality rates of 7 percent in the group receiving hyperbaric oxygen (n = 14) versus 42 percent in the group not receiving hyperbaric oxygen (n = 12). Overall mortality was 23 percent. Controversy still surrounds disease pathogenesis in Fournier's gangrene, particularly in regard to etiology. Our study corroborates current trends in that a clear focus or origin was identified in a majority of the cases. Although a grim prognosis usually accompanies the diagnosis, this study shows significant improvement combining traditional surgical and antibiotic regimens with hyperbaric oxygen therapy.

Traumatic injuries of the female external genitalia and their association with urological injuries.

PURPOSE: To date trauma to the female external genitalia has been incompletely characterized. At our institution a large number of such patients have been identified and many had associated urological injuries. We characterize these injuries and their association with urological injuries. MATERIALS AND METHODS: We reviewed the charts of all female patients presenting with trauma to the genitalia unrelated to parturition between 1991 and 1996. Type and mechanism of injury, associated injuries and blood transfusion requirements were noted. Vaginal injuries were classified as complex (greater than 3 cm., multiple or involving deeper structures) or simple (all others). RESULTS: We identified 20 women a mean 20.7 years old with traumatic injuries to the genitalia, including motor vehicle accidents in 6, injury from consensual intercourse in 5, sexual assault in 4 and other penetrating injuries in 5. There were 15 patients with vaginal injuries (complex in 8 and simple in 7) and vulvar injuries in 5. Six of the 20 women (30%) had associated urological injuries (urethra in 1, bladder in 4, ureter in 1 and kidney in 3) [corrected], including 3 associated with blunt trauma (all complex vaginal injuries) and 3 associated with penetrating trauma (simple vaginal or vulvar injuries). CONCLUSIONS: Traumatic injury to the female genitalia unrelated to parturition is more common than previously reported. Of the women with such injuries 30% have coexisting urological injuries. Thus, it is important to assess completely all women who present with external genitalia trauma for possible coexisting urological injury.
