Laparoscopic urinary diversion.

Urinary diversion, in conjunction with cystectomy or as an isolated procedure, has traditionally been performed using open surgical technique. Laparoscopic urinary diversion has only recently been reported. We review the available literature on laparoscopic urinary diversion and present some of the experimental and clinical studies that have attempted to overcome the technical difficulties of the procedure. In addition, the indications, results, and future directions of laparoscopic urinary diversion are discussed.

Management of late complications of the Kock pouch form of urinary diversion.

Urinary diversion via the continent ileal reservoir has been performed at our institution since 1982. During a 3-year period 250 patients have sought this procedure as an alternative to other forms of cutaneous urinary diversion. We analyzed our data in terms of late complications resulting directly from the operation or from this form of urinary diversion. In this context 77 of the 245 patients who survived the operation have suffered 1 or more late complications, requiring 85 reoperations. The late complications mainly have involved problems with continence or ease of catheterization and they were detected within 6 months. We report our experience and describe the technical aspects of treatment.

Absorption of vitamin B12 administered to continent ileal reservoirs for urinary diversion.

Urinary diversion through intestinal segments is a widely used method after radical cystectomy. During the last few years, new methods of bladder substitution, continent ileal neobladders, were developed. We used the method described by Hautmann et al. in 1986. 70 cm of ileum is used to form a reservoir. The ureters are implanted into the reservoir, which is then anastomosed to the urethral stump. A known problem when intestine is used for urinary diversion is the absorption of urinary solutes leading to metabolic disturbances. Therefore, the absorption of vitamin B12, instilled into the neobladders of 20 patients, was measured and related to the postoperative interval. The results show a high absorption rate 2 weeks postoperatively that is reduced quickly and significantly (p < 0.001) within the first 10 months (from more than 30 to below 5%). One year to 23 months after the operation, some neobladders absorbed no vitamin B12 at all, whereas others still absorbed significantly but only small quantities. These results may probably be attributed to the loss of villous structure as well as atrophy of the epithelial surface.

Relative indications for orthotopic lower urinary tract reconstruction, continent urinary diversion and conduit urinary diversion.

Continent urinary diversion has become increasingly popular in the last few years and there are now several situations in which ileal conduit diversion, continent diversion and orthotopic reconstruction of the lower urinary tract are equally valid options. This review was intended to determine specific indications for each. Of 513 patients treated for severe lower urinary tract problems in the last 10 years, 399 underwent orthotopic reconstruction, 68 underwent continent diversion and 46 had an ileal conduit. Problems occurred 2 to 3 times more commonly in the continent diversion group than in either of the other groups. Given a free choice, most patients would choose an orthotopic reconstruction and this should probably be regarded as the gold standard. Continent diversion is specifically indicated in male patients who require a total cystourethrectomy for bladder cancer, in severe post-radiotherapy problems, and in patients with neuropathic bladder dysfunction in whom, for various reasons, self-catheterisation is impossible. Ileal conduit diversion remains the simplest and safest technique in high-risk patients and does not preclude a subsequent continent diversion or orthotopic reconstruction.

Use of the ileocecal segment for bladder substitution or continent urinary diversion.

Urinary reservoirs constructed from the ileocecal segment conform generally to the principles of an ideal bladder substitute. They have psychological and functional advantages for selected patients who require urinary diversion. The reservoir can easily be placed in the pelvis attached to the urethra. Alternatively, an extremely efficient efferent continence mechanism that is both easy to catheterize and to construct can be made from tapered terminal ileum and an intact ileocecal valve.

Urinary tract stones: a complication of the Kock pouch continent urinary diversion.

Urinary tract stone disease has been found to be a later complication associated with the construction of the Kock pouch continent urinary diversion. Of 383 patients who underwent Kock pouch diversion between August 1982 and December 1986 stones developed in the pouch in 64 (16.7%), usually on exposed staples or eroded Marlex used to construct the nipple valves. Stones have recurred in 13 of the 64 patients (22%). Most stones were removed endoscopically with techniques similar to those used for percutaneous stone removal. Risk factors for stone formation include Marlex collar erosion and acute pyelonephritis. Changes in surgical techniques with elimination of the Marlex collar and a reduction in the number of staples have reduced the incidence of this later complication to 10%.

[Examination of the risk factors for infectious urolithiasis formation in patients receiving urinary diversion or urinary reconstruction using intestine--comparison of reservoir and ileal conduit].

Urinary risk factors and preventive factors for infectious calcium (Ca) urolithiasis formation, such as citrate, oxalate, Ca, phosphate, magnesium, and uric acid were examined more than 2 months after performing a urinary reservoir in 12 patients (R group) and ileal conduit in 10 patients (C group). There was no difference in the positive rate of risk factors between the two groups and also no difference in the positive rate of more than two risk factors between the two groups. Although four patients with more than two risk factors in the R group suffered from reservoir stones all of which included Ca-urolithiasis, none in the C group did. In the R group, the incidence of stone formation in patients with 2 or more risk factors was significantly higher than those in patients with 1 or no risk factor. In conclusion, the urinary reservoir operation should not be carried out in patients with more than two risk factors for urolithiasis formation, and urinary risk factors should be examined before reservoir operation.

Use of single J urinary diversion stents in intestinal urinary diversion.

A review of the past twenty months of intestinal-urinary diversion with use of the single J urinary diversion stents at Albany Medical Center Hospital and the Albany Veterans Administration Medical Center resulted in no ureteroileal anastomotic fistulas. Thirty-seven stented anastomoses were performed in 19 patients.

Quality of life survey of urinary diversion patients: comparison of continent urinary diversion versus ileal conduit.

BACKGROUND: Continent urinary reservoirs (CUR) have become one of the major options for patients requiring urinary diversion to improve their quality of life (QOL). To assess whether CUR enhanced postoperative QOL, we surveyed patients with CUR and ileal conduit (IC) using a questionnaire sent by mail. PATIENTS AND METHODS: The questionnaire consisted of 133 questions that covered physical and mental status, social life, sexual habits and symptoms related to urinary diversions. A total of 172 questionnaires were sent out, and 137 (80%) patients (74 CUR and 63 IC patients) responded. RESULTS: Basic physical conditions were similar in the 2 groups, except for sleeping habits. Regarding social life, however, the CUR group showed better scores in bathing habits and frequency of overnight travel. Parastomal dermatitis was more frequent in the IC group and the patients were more hesitant to show their stoma to others. On the other hand, about half of the patients in the CUR group complained of troublesomeness in self-catheterization, especially at night. Overall, 74% and 41% of the patients in the CUR and IC group were satisfied with their urinary diversion. When the Kock pouch and Indiana pouch were compared, no statistically significant differences were found in average capacity, maximum capacity, or frequency of self-catheterization. CONCLUSIONS: CUR recipients have enhanced QOL regarding the stoma, travel and sleeping habits as compared to ileal conduit. However, troublesomeness of night time self-catheterization was noted in the CUR group. Individualized selection of the type of urinary diversion with informed consent is essential.

Distressful symptoms after radical cystectomy with urinary diversion for urinary bladder cancer: a Swedish population-based study.

OBJECTIVE: To study the excess prevalence of distressful symptoms after radical surgery for urinary bladder cancer. METHODS: We included all patients who underwent cystectomy due to bladder cancer before 1996 in Stockholm County. A control group was randomly selected from the general population. Information was collected by means of an anonymous postal questionnaire. RESULTS: Completed questionnaires were returned by 310 (71%) controls and 251 (85%) cystectomized individuals. A 5-fold (reservoir) and 9-fold (conduit) increase in defecation urgency and a 4-fold (reservoir) and 6-fold (conduit) increase in faecal leakage were reported in individuals operated on. Urinary tract infection was increased 3-fold in cystectomized individuals compared with controls, during the previous year 26% of the patients reported a symptomatic infection. The perception of a reduced physical attractiveness due to disease was more than 5-fold increased in the men operated on compared to the controls. The majority, 135 out of 201 (67%), reported that they would have refused alternative bladder-sparing procedures if they decreased the prospects of survival by even as little as 1%. CONCLUSIONS: The patient's situation after cystectomy is considerably impaired due to changed bowel and sexual function, urinary tract infections and a sense of decreased attractiveness. However, most patients are in spite of this unwilling to compromise survival.

[Current practice and controversies in urinary diversion--the selection of the operation method of urinary diversion and postoperative care].

Since Kock et al. reported a low pressure continent reservoir using detubularized ileal segment as urinary diversion following cystectomy, continent urinary diversion including neobladder has been focused upon. On the other hand, ureterocutaneostomy, or ileal conduit as an incontinent urinary diversion is still commonly used, and especially the latter form is usually performed in many hospitals. These facts suggest that it is difficult to conclude that continent urinary diversion regarded as an excellent operation with good quality of life (QOL) is a generally acceptable method and that there are still some problems to decide the indication for urinary diversion. We discuss the problems about the postoperative complications and care of urinary diversion after cystectomy and our opinion about the selection of these operations.

Quality of life and health in patients with urinary diversion: a comparison of incontinent versus continent urinary diversion.

OBJECTIVE: To compare the quality of life and health in patients with incontinent and continent urinary diversions, in correlation with the initial diagnosis, diversion-related symptoms, psychological status and employment status. MATERIALS AND METHODS: 81 patients (64% male and 36% female) with a mean age of 55 years (18-65 years) were included in this retrospective study. A total of 27 had an incontinent urinary diversion (group A) and 54 a continent diversion (group B). The initial diagnosis was malignant tumor in 75% (n = 61) and nontumor disease in 25% (n = 20). A structured interview and psychometric instrument assessment of the quality of life as well as somatic and psychological symptoms were carried out and analyzed. RESULTS: Patients with nontumor disease, a continent reservoir and employment tended to have the highest level of quality of life. The higher the number and severity of psychological symptoms, such as depression and anxiety, the lower the level of global satisfaction with life, health and urinary diversion, and vice versa. No difference was seen between groups A and B concerning diversion-related symptoms, global satisfaction with life and health and sociodemographic data. CONCLUSIONS: The decision for a continent versus an incontinent urinary diversion must consider not only the medical factors of each individual patient, but also the initial diagnosis, psychological condition and employment status.

Conduit urinary diversion and urinary-tract infection. II. Raised serum antibody titers against Escherichia coli and Proteus mirabilis in relation to bacteriologic findings.

Elevated serum antibody titers against Escherichia coli and/or Proteus mirabilis were found in 35% of 89 patients with a conduit urinary diversion. Statistical analysis showed significant correlation between the titers and growth of E. coli or P. mirabilis in conduit urine. But 17 (24%) of 72 patients without E. coli in urine cultures had raised E. coli antibody titer. Only 3 (4%) of 68 patients without growth of P. mirabilis had raised P. mirabilis antibody titer. When the post-diversion observation period was more than five years, the frequency of antibody titer elevation was greater than in patients with shorter post-diversion follow-up. The volume of residual urine in the conduit showed statistically significant correlation with presence of bacteriuria and with the antibody titer level against P. mirabilis. Patients with high antibody titers tended to have high readings of serum creatinine. Antibiotic therapy reduced elevated E. coli and P. mirabilis antibody titers. Titration of antibodies to E. coli and P. mirabilis is recommended in the follow-up care of patients with conduit urinary diversion.

Long-term metabolic effects of urinary diversion: a comparison of myelomeningocele patients managed by clean intermittent catheterization and urinary diversion.

We previously reported that chronic urinary diversion through intestinal segments may have adverse effects on bone and mineral metabolism. This study examined the long-term health of patients managed by urinary diversion (94% by ileal conduit) for neuropathic bladders secondary to myelomeningocele defects and compared them to a control population of myelomeningocele patients managed by intermittent catheterization. Of the patients 93 were studied by personal interview, chart review, morphometric analysis, serum studies and dual-photon bone density determination. Average followup was 23 +/- 6 years in the urinary diversion group and 17 +/- 5 years in the intermittent catheterization group. Fractures occurred in 40% of the patients in both groups. Patients with a urinary diversion had an increased need for surgery to correct spinal curvature (57% versus 40%) and a significantly increased incidence of complications resulting from orthopedic procedures (17% versus 3%, p less than or equal to 0.05). There was also an adverse effect on renal function. The urinary diversion group had an increased incidence of radiographic renal deterioration (57% versus 8%, p less than 0.001), nephrolithiasis (43% versus 2%, p less than 0.001), pyelonephritis (60% versus 21%, p less than 0.001) and intermittent metabolic acidosis (20% versus 5%, p = 0.05). Surgery was required in 37% for stomal complications and in 17% for ureterointestinal stricture. Linear growth was adversely affected by urinary diversion. Patients with urinary diversion had decreased lengths for all morphometric parameters and a greater percentage of them were at or below the 10th percentile standards. Serum electrolytes, liver function studies, vitamin D3 and parahormone showed no differences in the 2 groups. No patient had a significant metabolic acidosis at the time of study. Bone densities were significantly diminished in both groups and not significantly different. This study strongly suggests that urinary diversion through intestinal segments is associated with adverse effects on bone health.

Simple cystectomy in patients requiring urinary diversion.

PURPOSE: Urinary diversion is an alternative treatment for conditions such as radiation and interstitial cystitis, neurogenic bladder and severe incontinence. The subsequent complication rate may reach 60% due to the retained nonfunctional bladder. The subsequent cystectomy rate may be as high as 20% because of pyocystis, hematuria, pelvic pain and rarely bladder cancer. We describe simple cystectomy involving bladder removal without the adjacent structures, avoiding deep pelvic dissection. MATERIALS AND METHODS: Ileal conduit or continent diversion and simple cystectomy were performed for crippling bladder symptoms secondary to neurogenic bladder, pelvic radiation, hematuria and/or severe incontinence in 12 women and 7 men with a mean age of 63 years. We performed urinary diversion and simple cystectomy only when all conservative means of treatment had failed. The majority of patients had multiple co-morbidities, previous surgeries and pelvic radiation. An average of 5 conservative procedures (range 2 to 10) had been done before simple cystectomy. None of these patients had urothelial malignancy. Simple cystectomy was done concomitantly with urinary diversion in 13 cases and later as a separate procedure in 6 due to complications of a retained nonfunctional bladder. RESULTS: Mean followup was 15 months. No mortality was associated with surgery. For simple cystectomy only mean operative time was 30 minutes and mean estimated blood loss was 300 cc. Median time from symptom presentation to cystectomy was 35 months and mean hospital stay was 7 days. In all cases symptoms were dramatically alleviated. No morbidity was directly attributable to simple cystectomy. CONCLUSIONS: Simple cystectomy is well tolerated and should be performed at urinary diversion to avoid later complications of the retained bladder. Technically this procedure is not demanding and is relatively easy to perform even after previous pelvic radiation.

[Complications of continent urinary diversion].

Continent urinary diversion over its advantages, in comparison with incontinent urinary diversion, has serious complications. The authors analyse results and complications, which they registered in 26 patients 10-50 (average 20) months after supravesical continent urinary diversion. The commonest complications were in connection with the continent mechanism, these lead in 8 patients to urinary incontinence. Other serious complications were reservoir perforation during catheterisation in 3 and development of stones in the reservoir in 2 patients. All these major complications necessitated reoperation.

Pregnancy after orthotopic continent urinary diversion.

Continent urinary diversion has become a common form of bladder management for the female exstrophy patient in whom primary reconstruction has failed. Reported are the results of successful pregnancies in four young adult females, who had previously undergone a flap vaginoplasty as part of earlier management and more recently a continent right colonic urinary reservoir with a perineal stoma (Indiana pouch). Pregnancy in each of these patients was characterized by several urinary tract infections, cervical prolapse and mild to severe maternal hydronephrosis. All of the patients had some degree of difficulty with clean intermittent catheterization. One patient required an indwelling catheter with prolonged bed rest. Maternal hydronephrosis resolved after delivery in all instances. All four patients delivered their infants by way of cesarean section, either emergently for maternal or fetal distress or electively. Cervical prolapse did not resolve in three patients and will require surgical repair. After delivery, all patients returned to their previous pattern of clean intermittent catheterization without loss of continence. All the infants delivered were healthy with appropriate weights and high Apgar scores (more than 8). Orthotopic (perineal stoma) continent urinary diversion is not a contraindication to pregnancy. However, our experience mandates delivery by cesarean section with close monitoring for maternal or fetal distress during gestation.
