1/9. Endoscopic management of prolapsing intravesical ureterocele in an adult female--a case report.

    The authors present a case of intravesical ureterocele in a female which prolapsed out of the external urethral meatus causing urinary obstruction, and was managed by reduction into the bladder followed by endoincision.

2/9. In-utero treatment of fetal bladder-outlet obstruction by a ureterocele.

    Fetal bladder-outlet obstruction by ureteroceles is usually treated at birth. However, such obstruction may be detrimental to the health of the fetus and so in-utero correction is preferable. We describe the successful cytoscopy guided laser incision, with no complications, of a uterocele that was causing bladder-outlet obstruction in a fetus of 19 weeks and 6 days gestation.

3/9. Bladder outlet obstruction after operation for ureterocele.

    Two patients with ureterocele-induced bladder outlet obstruction are presented. In each instance, a broad-based diverticulum had developed in the floor of the bladder as a result of the muscular defect created by a simple ureterocele in one patient and an ectopic ureterocele in the other. This bladder diverticulum produced secondary obstruction of the bladder outlet during the act of voiding. urinary diversion in one patient had been carried out because of bladder outlet obstruction and was being seriously considered in the other patient because of upper tract deterioration. After the correct diagnosis was established, reconstruction of the muscular defect eliminated the obstruction and reestablished satisfactory bladder function. urinary diversion was thus prevented in one patient and undiversion accomplished in another, when the true obstructing nature of the bladder diverticulum was established and correct therapy instituted.

4/9. Low transurethral incision of single system intravesical ureteroceles in children.

    Single system intravesical ureteroceles in children usually result in various degrees of hydroureteronephrosis requiring surgical intervention to provide drainage, decompression and preservation of renal function. Our experience with 7 symptomatic single system ureteroceles in 5 children managed by low transverse endoscopic ureterocele incision is reviewed. After endoscopic incision, hydroureteronephrosis decreased in all patients. Vesicoureteral reflux after incision was noted in only 1 kidney. The technique of short (2 to 3 mm.) low transverse ureterocele incision is recommended for the initial management of single system ureteroceles to relieve obstruction. Preservation of the flap valve ureteral antireflux mechanism is possible in most children. The technique is simply performed, can be safely done in the youngest child and, in many, obviates the need for a further operation.

5/9. Ultrasonographic appearance of a simple ureterocele following surgical treatment.

    A case history is presented, showing the ultrasonographic appearance of a simple ureterocele following surgery. The cystic appearance of the presurgical ureterocele and the gradual changes after surgery are demonstrated. Follow-up examination 17 months after surgical treatment revealed a solid tumour-like ultrasonographic image. Differential diagnosis to neoplasma of the urinary bladder is emphasized.

6/9. Transitional cell carcinoma occurring in ureterocele.

    A case of transitional cell cancer developing in a ureterocele stump several years after a heminephroureterectomy is described. The role of ultrasonography in establishing the diagnosis is emphasized. This case illustrates the potentially dangerous effect of leaving a defunctionalized ureteral stump and ureterocele. Recommendation is made for removal of the ureteral stump and ureterocele at the time of heminephroureterectomy to prevent the aforementioned complication.

7/9. Ipsilateral ureteroureterostomy for single ureteral disease in patients with ureteral duplication: a review of 8 years of experience with 16 patients.

    Ipsilateral ureteroureterostomy near the bladder (end-to-side anastomosis) for treatment of single ureteral disease in patients with complete ureteral duplication has been performed in 16 patients during the last 8 years. The operative technique, indications, results, followup and complications are presented. Reflux in the lower segment ureter was treated in 13 patients and upper segment ectopia or ureterocele was managed in 3 patients with this operative procedure. This operative technique is simpler and safer than reimplantation of both ureters into the bladder. Because no dissection of the bladder wall is needed there is less risk of injury to the pelvic viscera and vasculature. The chance of success in correcting reflux appears better than with reimplantation of both ureters into the bladder. Long-term followup has shown few complications and no repeat operations were needed in this series. The small stump of the diseased ureter left behind near the bladder caused no serious problems.

8/9. Bilateral intravesical duplex system ureteroceles with multiple calculi in an adult patient.

    We present a case report of an adult female patient with bilateral duplex system ureteroceles, containing multiple small stones. There was no history of urinary tract infections or stone disease. Treatment consisted of right upper pole heminephrectomy because of non-function and transurethral incision of the left ureterocele, resulting in almost complete removal of the calculi. Furthermore no vesicoureteral reflux was seen 3 months postoperatively. Transurethral incision is a safe and effective treatment in removing stones in ureteroceles without necessitating further treatment because of vesicoureteral reflux.

9/9. Construction of a female urethra using the vaginal wall and a buttock flap: experience with 40 cases.

    methods: From 1975 to 1996 a urethra was constructed using tubularized anterior vaginal wall covered with a buttock flap in 40 female patients in whom urinary incontinence was associated with a short or absent urethra. The underlying pathology included bilateral single ectopic ureters, cloacal malformation, urogenital sinus malformation, previous failed surgery of the urethra, severe trauma, myelodysplasia, female hypospadias, ectopic ureterocele with destruction of the urethra, congenital epispadias, bladder exstrophy, and previous hysterectomy and vaginectomy for clear cell carcinoma caused by intrauterine exposure to diethylstilbestrol. Other reconstructive procedures in these patients included bladder neck narrowing from above in 33 patients, ureteral reimplantation in 35, and bladder augmentation in 21. In the prone position, a tube of vaginal wall was used to create a urethra when it was absent or lengthen the urethra if it was too short. The neourethra was extended up to the base of the clitoris, using a multilayered closure of soft tissue over it distally with introital muscle and adjacent mucosa. The proximal neourethra was covered with a buttock flap. RESULTS: All patients were originally wet. Thirty-four are now dry. Four patients have minimal stress incontinence. Two patients have urinary diversions. The majority (n=25) void normally. Fourteen patients self-catheterize to empty their bladders. One patient wears an external appliance on the abdominal wall for collection of urine. Complications included: creating stress incontinence in one patient who had been previously dry by extracting a stone from the bladder, necrosis of a buttock flap from applying a tight perineal dressing, fistula requiring surgical closure in three patients, and slippage of the buttock flap in one patient. CONCLUSION: This operation is a useful method to correct diverse congenital and acquired pathology that causes incontinence in girls.
