After failure of conservative treatment of neurogenic bladders (deterioration of the upper urinary tract/incontinence) continent cutaneous diversion has to be considered in those patients with irreparable urethral sphincter defects or those who are unable to perform trans-urethral self-catheterization. In this second part of the study we investigated the long-term safety of using the Mainz pouch I with regard to protecting the upper urinary tracts and to provide urine continence. Between 1985 and 2002, operations to form an ileocaecal pouch with umbilical stoma (Mainz pouch I) were performed on 70 children and adolescents of median age 15.3 years (range 5.7-20 years). During the follow-up period five patients died 2.4-14 years postoperatively of causes not related to urinary diversion. A follow-up period of 8.7 years (0.9-18) was achieved in 65 patients with 118 renal units (RUs). As compared to preoperatively, the upper urinary tracts had remained stable or improved in 113/118 RUs (95.8%) at the latest follow-up. Complete continence was achieved in 97% of patients with a continent cutaneous diversion. Surgical revisions were required for: incontinence of the outlet mechanism in 9%, stoma prolapse in 2%, stoma stenosis in 23%, pouch calculi in 15%, symptomatic reflux in 1%, ureter stenosis in 16% of the RUs with submucosal tunnel and in 3% of the RUs with an extramural tunnel. We conclude that, in patients with irreparable sphincter defect and those who are unable to perform urethral self-catheterization, continent cutaneous urinary diversion with the Mainz pouch I provides a high continence rate with preservation of the upper urinary tracts in the long run. In patients with dilated ureters, the extramural tunnel technique results in a lower complication rate.

In our case report we present the course of diagnosis and treatment of primary urinary incontinence in a girl aged 14. In abdominal ultrasound examination we found features of double renal pelvis on the left side. Intravenous urography confirmed that anatomical variant. Moreover it gave the suggestion of duplicated left ureter. Regarding the clinical data and the results of ultrasonography and urography, we suspected that the symptoms might be connected with the ectopic orifice of one from the left ureters, probably that one associated with the upper renal pelvis. We managed to find this ectopic ureteral orifice in the vaginal vestibule. But when we performed antegrade pyelography through that orifice, we found that it constituted the ending of additional right ureter, which was not imaged in previous examinations. That diagnosis was very unexpected. The child was operated on. During the operation a small, hypoplastic additional right kidney was discovered. That kidney was excised together with the ectopic ureter. The urine incontinence stopped immediately after the operation.

Persistent incontinence after toilet training in young girls and urinary tract infections or epididymitis in prepubertal boys should raise suspicion of an ectopic ureter. This often occurs in the context of duplication of kidney structures or other parenchymal abnormalities. The presence or absence of reflux affects surgical treatment, which may consist of ureteral reimplantation, ureteroureterostomy, and/or upper pole nephrectomy.

Ectopic ureter accounts with an incidence of 1 in 2000 newborns. When present, ectopic ureter can be associated with duplex kidneys in an 85 % of the cases. Clinical manifestations of this malformation include incontinence and urinary tract infections. Ectopic ureter frequently occurs in association with a dysplastic upper pole renal moiety. When a poorly functioning upper pole segment is present, a standard surgical treatment is upper pole heminephrectomy. A 23-years old woman presented with left renal colic pain, fever and urinary leak. Ultrasound, intravenous pyelogram and antegrade pyelogram revealed a partial duplex right kidney and a complete duplex left kidney with hydronephrosis and ectopic insertion into the urethra of the left upper pole moiety. Following diagnosis upper pole heminephrectomy and partial ureterectomy was performed.

Despite the reports of a number of leading institutions concerning the use of primary exenteration, there are differences in regard to definition, indications, and interpretation of results of this treatment approach to cervical cancer. In this paper we present our own experience with 41 cervical cancer patients treated with primary exenteration at St. Stephen Hospital Budapest. We explore some important unsettled aspects (definition, indications, and quality of life consequences) of this treatment modality in view of our own experience and the literature. Between January 1993 and June 2006, 2540 invasive cervical cancer patients were seen at the gynecologic oncology service of the St. Stephens Hospital Budapest. Two hundred twelve (8%) of these patients were surgically explored with the plan of an exenterative surgery. Exenteration was the primary treatment in 41 (25%) of 166 completed exenterations; these 41 cases included 2 cases of supralevator total exenteration, 9 cases of supralevator anterior exenteration, and 30 cases of partial supralevator anterior exenteration. In the 2 total exenteration patients, anal function was restored with a low rectal anastomosis, with a temporary defunctioning colostomy in 1 patient. Urethral function was restored in 9 out of 11 supralevator exenteration cases with the Budapest pouch bladder replacement technique. In the remaining 2 cases, a Bricker conduit was used for urinary diversion. There was no operation-related mortality in this cohort of patients. An external fecal or urinary stoma was avoided in 38 (93%) out of the 41 primary exenteration patients; in 1 patient a temporary defunctioning colostomy was used; and in 2 patients a permanent ileal conduit was created. In 9 patients (22%), complications (ileus and peritonitis, occlusion of the femoral artery, stricture of the implanted ureter, and postoperative ureterovaginal fistula) necessitated surgical intervention. A quality of life study revealed the need for prolonged self-catheterization, partial (mainly night time) incontinence, and lymphedema in 7 patients. We consider and suggest that an en bloc resection of part(s) of the urinary bladder and/or the rectum with the uterine cervix should be considered an exenteration (partial exenteration). A 50% survival rate of a select group of stage IVA cervical cancer patients treated with primary exenteration can be considered significant, but cannot be considered superior to that of chemoradiation therapy. The same applies when considering treatment-related mortality and complications that require operative interventions. Low rectal anastomosis and orthotopic bladder replacement with a relative low risk of fistula formation in non-irradiated patients constitute a strong quality of life argument in favor of primary exenteration in a select group of stage IVA cervical cancer patients.

45 girls with extravesical ureter ectopy of double kidneys were treated outpatiently for 1981-2006. Their age varied from 6 months to 15 years. The anomaly was right-sided in 12 children, left-sided in 27 and bilateral in 6 cases. All the patients underwent surgical cor--rection: upper heminephrureterectomy was performed in 35 cases, nephrectomy--in 5 cases, ureteropyeloanastomosis--in 1 case, ureter-ureter anastomosis in the upper one third--in 3 cases and ureter-neo-cystoanastomosis in 1 child. We propose a new diagnostic method for estimation of functional state of the upper part of the double kidney with extravesical ectopy of its ureter. The method is based on comparison of volumes for 24 hour urine collection in natural urination and urinary incontinence, determination of relative density of urine collected in incontinence. If ectopic volume makes 19% and more of normal micturition volume and density of this urine is more than 1014, function of the upper part is good and organ-sparing surgery is indicated. Good results of 1 to 24 year follow-up were achieved in all the patients.

Urinary incontinence--loss of voluntary control over the retention and expulsion of urine--is a common medical problem in small animal patients. Incontinence occur when pressure within the bladder exceeds urethral pressure. Incontinence may result from a variety of etiologies, including congenital anatomic abnormalities of the lower urinary and reproductive systems (ureter, bladder, bladder neck, urethra, vagina,vestibule) as well as neurologic, neoplastic, infectious, and inflammatory disease.

An ectopic vaginal ureter is an infrequent cause of urinary incontinence. Most cases are associated with a duplex kidney in which the lower moiety ureter drains into the bladder. Occasionally, some cases of ectopic kidney with single vaginal ectopic ureter can occur. In this study, we present a case of chronic continuous urine incontinence caused by the extremely rare combination of a fused-crossed kidney and a single vaginal ectopic ureter. Laparoscopic nephroureterectomy was carried out smoothly and uneventfully. In our experience, laparoscopic navigation and surgery can be valuable tools to delineate and manage unusual congenital anomalies.

Normal physiologic function of the pelvic organs depends on the anatomic integrity and proper interaction among the pelvic structures, the pelvic floor support components, and the nervous system. Pelvic floor dysfunction includes urinary and anal incontinence; pelvic organ prolapse; and sexual, voiding, and defecatory dysfunction. Understanding the anatomy and proper interaction among the support components is essential to diagnose and treat pelvic floor dysfunction. The primary aim of this article is to provide an updated review of pelvic support anatomy with clinical correlations. In addition, surgical spaces of interest to the gynecologic surgeon and the course of the pelvic ureter are described. Several concepts reviewed in this article are derived and modified from a previous review of pelvic support anatomy.

A 45-year-old woman was admitted to our hospital with a chief complaint of stress urinary incontinence. She had undergone simple hysterectomy due to myoma uteri at another hospital. X-ray examination and ultrasonography revealed a hydronephrosis on the right side after the surgery, which was improved immediately without intervention. She was diagnosed as having stress incontinence according to the history, findings of frequency/volume chart, 1-hour pad test, cystoscopy, drip infusion pyelography, magnetic resonance imaging and so on. Periurethral injection with non-animal stabilized hyaluronic acid/ dextranomer was performed. Incontinence was improved, but was not cured completely. After indigo carmine intravenous injection, cystoscopy was performed but no urine flow was noted from the right ureteral orfice. At the transvesical investigation, blue fluid was found at the vagina, and she then was diagnosed as having right ureterovaginal fistula. She underwent ureterovaginal fistula repair and reimplantation of the right ureter, and her incontinence was cured. To our knowledge, this is the first case of ureterovaginal fistula associated with stress incontinence.
