Diagnosis and treatment of ejaculatory duct obstruction in male infertility.

OBJECTIVE: To discuss the diagnosis and treatment of ejaculatory duct obstruction in male infertility. PATIENTS AND METHODS: Twenty-four males were treated for ejaculatory duct obstruction between 1994 and 1998 in our clinic. Patients' age varied between 20 and 40 (mean=29). Ejaculatory duct obstruction was considered in patients with low to normal ejaculate volume, azoospermia or oligospermia, decreased motility, normal serum gonadotropin and testosterone levels, absent or low fructose in the ejaculate and evidence of obstruction on transrectal ultrasonography. The definitive diagnosis was made by the absence of efflux of methylene blue injected through the vas during cytoscopy. All the patients were subjected to transurethral resection of ejaculatory ducts and spermograms before and 3 months after resection were compared. RESULTS: Before transurethral resection mean sperm count was 1.66x10(6)/ml compared to 25.4x10(6)/ml postoperatively. The difference was statistically significant (p=0.001). After the operation, 58.3% of the cases had improvement in sperm motility, and 62.5% had increased ejaculate volume. No significant complications occurred, and in only 1 (4.17%) patient, there was persistent hematuria. After a mean follow-up period of 9 (6-18) months, 6 (25%) pregnancies were noted. CONCLUSION: Although transurethral resection is an effective method for the treatment of ejaculatory duct obstruction, the pregnancy rate is low, which could be related to the hazardous effects of urinary reflux into ejaculatory ducts or functional abnormalities of seminal vesicles.

Use of bladder mucosal graft for urethral reconstruction.

BACKGROUND: The ideal tissue for complex urethral reconstruction has yet to be determined, especially in patients with deficient preputium. The use of bladder mucosa as a free graft could be an alternative in these problem cases. METHODS: Bladder mucosa graft urethroplasty was performed on 14 patients with penoscrotal or scrotal hypospadias. The mean age of the patients was 18.7 (range 14-23) years. Ten cases were subjected to primary urethral reconstruction while four cases had previous hypospadias repair. RESULTS: Complete urethral replacement by the bladder mucosa tube was performed in six patients. Meatal problems occurred in two (33.33%) patients and proximal fistula formed in one (16.67%) patient. A bladder mucosa graft was combined with preputial or tunica vaginalis grafts distally in eight cases, and one patient in the tunica vaginalis group developed fistula at the anastomosis of the bladder mucosa and tunica vaginalis grafts. The overall complication rate was 28.6%. CONCLUSIONS: Our initial results showed that bladder mucosa grafts can be used successfully for urethral reconstruction especially when combined with preputial or tunica vaginalis grafts distally.

Ureterocystoplasty in bilaterally functional kidneys.

OBJECTIVE: Traditional augmentation cystoplasty using gastrointestinal segments is known to be associated with metabolic abnormalities and alterations in the bladder causing potential carcinogenesis. In this respect alternative techniques have been searched preferably lined by urothelium. We performed ureterocystoplasty in 7 patients with a diagnosis of neurogenic bladder and investigated the clinical and functional aspects. PATIENTS AND METHODS: Between 1995 and 1999, ureterocystoplasty was performed using both ureters in 4 male and 3 female children with bilaterally functional kidneys. Patients' ages varied between 1 and 7 (mean 4.7) years. Before the operation all the children were incontinent, had a small-capacity noncompliant bladder, and high-grade (IV-V, International Classification System) reflux on voiding cystouretrography (VCU). Technetium-99m DTPA renal scintigraphy was also performed in all children to evaluate renal function before and after the operation. RESULTS: Before the operation the mean end-filling intravesical pressure was 45.6 (35-60) cm H(2)O which decreased to 18.9 cm H(2)O 3 months postoperatively. The mean bladder capacity 3 months after ureterocystoplasty was found to be 279.3 (250-330) ml. All the children were continent and VCU showed the absence of reflux. There was mild to moderate improvement in renal function after surgery in both kidneys on technetium-99m DTPA renal scintigraphy. Three (43%) patients could void spontaneously with abdominal straining, whereas 4 (57%) children could empty their bladders by clean intermittent catheterization. A double-J stent was inserted in 1 (14%) patient because of a rise in serum creatinine after the removal of the ureteral catheter. Patients were followed for a mean period of 30 (8-50) months and all the children remained continent. The bladder capacity and end-filling pressure measurements were also stable. CONCLUSION: Ureterocystoplasty was found to be an effective method for bladder augmentation in bilaterally functional kidneys with an acceptable complication rate

Nephrogenic adenoma of the bladder after intravesical bacillus Calmette-Guérin treatment.

A 60-year-old female patient was subjected to transurethral resection of transitional cell carcinoma of the bladder and was given intravesical bacillus Calmette-Guérin treatment for 6 weeks. The control cytoscopy performed after 6 months revealed a polypoid lesion at the trigon and the lesion was resected. The pathological examination of the specimen showed no evidence of cancer but the presence of a metaplastic lesion that was nephrogenic adenoma.

[Missed ureteral injuries following surgical exploration with percutaneous nephrostomy and drainage treatment].

Twelve patients with missed ureteral injury and urinoma due to gunshot are evaluated following surgical exploration. All 12 had underwent surgical exploration at the other hospitals on admission. Fever, malaise, shocking chills, leucocytosis due to urinoma formation are the findings in the late postoperative period and CT (computer tomography) scan revealed urinoma. Intravenous urograms are nondiagnostic in 6 of patients and hematuria is detected in 6(%50) Percutaneous nephrostomy is emphasized as the first step of management for these lately diagnosed ureteral fistulas. Additionally, Urinoma is drained percutaneously. Hence we save the patients from a second operation following severe gunshot trauma. The presence of shock, intraoperative bleeding, colonic injury and blast effect of high velocity missile with delayed tissue necrosis are the cause of missed ureteral injury. At 8 patients, nephrostomy was the solution and total cure is achieved. Mean follow-up period after nephrostomy is 3 months. At 2, we perform psoas-hitch and ureteroneocystostomy, at one psoas-hitch, boary- flep and ureteroneocystostomy and at one ureteroureterostomy due to long ureteral obstruction on urinary fistula. As a conclusion, when treating missed ureteral injuries with urinary fistula and urinoma formation following complicated surgical intervention, percutaneous nephrostomy application and percutaneous drainage of urinoma may be the first step for management. Late surgical reconstitution is the second step when needed.

A new approach to bladder augmentation in children: seromuscular enterocystoplasty.

OBJECTIVE: To report the use of seromuscular enterocystoplasty (SE) combined with detrusorectomy, in children. PATIENTS AND METHODS: Between 1993 and 1998, SE was performed in 10 children (aged 10-17 years) with a spastic neurogenic bladder resulting from spinal trauma. Before surgery all children were incontinent and despite anticholinergic medication and clean intermittent catheterization, their bladder capacity was 60-100 mL and their intravesical pressure 40-60 cmH2O. RESULTS: Before surgery, the mean end-filling intravesical pressure was 47.7 cmH2O and the mean bladder capacity 82.9 mL. At 3 months after surgery the mean end-filling intravesical pressure was decreased to 21.1 cmH2O and the mean bladder capacity increased to 319.6 mL. One patient (a 14-year-old girl) had urinary retention soon after surgery and has since used clean intermittent catheterization. The other children were able to void successfully using the Valsalva manoeuvre; none were incontinent. All patients were followed and there were no changes in intravesical pressure and bladder capacity. CONCLUSION: In providing most of the desired features of an ideal augmentation segment, SE is a good and effective method of bladder augmentation.

Ultrastructural changes on sperm after extracorporeal shock wave lithotripsy in patients with distal ureteral stone.

Theoretically, ESWL can cause several side effects on the male reproductive system. We determined here the long-term effects of ESWL on sperm with transmission electron microscopy (TEM) in patients with distal ureteral stone. Fifteen men with stones in the distal ureter applied to our clinic formed the group of study. The other 15 men with renal or upper ureter stones formed the group of control. The ESWL sessions, including maximum 19 kW energy level and 3000 shock waves, were performed with Siemens Lithostar (electromagnetic; Siemens Medical Systems, Erlangen, Germany) lithotriptor. We examined the semen samples from all patients on the day before and 90 days after ESWL. The semen samples were examined with transmission electron microscopy (TEM) to detect ultrastructural changes on the day before and 90 days after ESWL. All the statistical analyses were realized with SPSS 10.0 (SPSS Inc., Chicago, USA) statistical package program. When the control and study groups were compared for initial and day 90 sperm concentration and motility, a significant decrease was found in the study group. Although there was no important anomaly in the control group, we determined some damage on sperm structure in 5 patients (33.3%) who are in the study group 3 months after ESWL. It can reduce sperm concentration and motility permanently. It can also cause severe ultrastructural defects on sperm after a long term period in patients with lower ureteral stone. Therefore, we suggest other treatment modalities for young men with distal ureteral stones to prevent the development of male infertility.

Reimplanted ureter as an alternative to the catheterizable Mitrofanoff tube.

OBJECTIVE: We performed this study in dogs to investigate whether a ureter can be used as an alternative to the appendix without disrupting the uniformity of the gastrointestinal system. MATERIALS AND METHODS: This study comprised 10 adult healthy female mongrel dogs. The procedure was done in 2 stages: in the first stage, we performed a left-end cutaneous ureterostomy at the lower left quadrant just above the inguinal ligament. A second operation was performed 6 weeks later. The left ureter was divided and using Paquin's technique, the proximal end of the distal third of the left ureter was reimplanted in the anterolateral surface near the dome of the bladder. A high transureteroureterostomy with the remaining left proximal ureter to the opposite ureter completed the reconstruction. The bladder neck was ligated in order to create an experimental bladder outlet obstruction. At the time of creating the distal ureteral stoma, a feeding tube was left in the bladder, passing through the ureterostomy stoma and sutured to the skin. This catheter remained in place for 20 days, preventing the bladder form distending. Then in the following 6 months, intermittent catheterization was applied through the stoma at 3- to 4-hour intervals. Exploration was performed at the end of the 6th month. RESULTS: No animal died. The dogs were still continent. Intravenous urography, urea and creatinin values were normal. The ureteral stoma was viable in all 10 cases. Stenosis of the ureteral stoma developed in 1 dog and required surgical revision. Possible traumatic effects were investigated by histological sections, but no harmful effects were found at the ureteral endothelium. CONCLUSION: This method may be an alternative to the Mitrofanoff method, which uses the appendix.
