Prolapse of a ureterocele through the external meatus is uncommon, and a prolapsed ureterocele occurring after upper pole heminephrectomy is extremely rare. We describe such a case, occurring 2 months after surgery. The ureterocele was excised with the upper pole ureteral stump, and the lower pole ureter was reimplanted with a good outcome.

The prevalence of obstructive uropathy linked to uterine prolapse ranges between 4% and 80%, depending on the series, probably due to the varying degree of severity of the prolapses under consideration. Renal failure or anuria is an unusual complication. Several etiopathogenic theories regarding obstructive uropathy secondary to prolapse have been put forward: ureteral compression by the uterine vessels, severe urethral angulation, ureteral compression against levator ani muscles and the elongation and narrowing of the distal ureter. The major radiological exploration used in studying the urinary tract of these patients is intravenous urography in bipedestation. Emergency treatment for obstructive anuria resulting from a uterine prolapse consists of manually replacement of the prolapse. Surgery is considered to be the definitive ideal treatment, although in the case of surgical or anaesthetic high risk patients, inserting a permanent pessary may constitute a satisfactory solution. We present a case of obstructive anuria resulting from uterine prolapse, which was successfully treated with the insertion of a ring pessary.

Different reconstructive operations were performed in 20 patients for intraoperative traumas of the urinary tract. 4 patients had injured ureter and urinary bladder. The damage was done in the course of obstetric operations (cesarean section, uterine extirpation). In 12 cases the ureter was injured in uterine extirpation for cancer (n = 4), myoma (n = 4), prolapse of the uterus, (n = 1), extirpation of uterine cervix stump (n = 1), ureteral electrocoagulation (n = 1) and adnexectomy (n = 1). In 4 cases ligation of the ureter complicated surgical interventions for cancer of the sigmoid colon (n = 1) and rectum (n = 1), diverticulosis of the colon (n = 1) and portal cirrhosis of the liver with evident cirrhosis (n = 1). Surgical policy in the treatment of intraoperative urinary tract injuries was organ-saving. Only in 3 patients with severe acute pyelonephritis surgery was two-staged with prior nephrostomy. In the rest cases primary reconstructive operations were made. Two patients with bilateral injury of the ureters after uterine extirpation have undergone transabdominal bilateral reimplantation of the ureters by Boari in Gregoir's modification. Reconstruction of pelvic ureter was often made by using a urinary bladder graft (Boari's technique). In 1 female patient with extensive vesicovaginal fistula resultant in detruzor corrugation sigmocystoplasty was made with a good result. Serious complications after the reconstruction were absent. Urinary fistulas formed in 4 cases. In 3 of them they closed without surgical intervention. In 1 patient, to close urinary fistula complicating ureterocystoanastomosis Boari's operation was conducted with a favourable outcome. Reconstructive operations saved the kidney function.

Intrascrotal hernia of the ureter is a rare event. We describe here one such case. There are two anatomic types of such ureteral hernias. The paraperitoneal type has a peritoneal indirect sac, which pulls the ureter with it. The extraperitoneal ureteral hernia is without a peritoneal sac. In such cases, which are almost always indirect hernias, there is usually a large amount of fat. It is, in fact, retroperitoneal fat, which slides, and pulls the ureter with it by gravity. Such a case is a genuine prolapse of the retroperitoneal structures. This anomaly, which has been rarely studied, is worth knowing about, because the ureter may be damaged during hernia dissection. The surgeon should be cautious when discovering huge fatty hernias, and should avoid the excision of fat and simply return the fatty mass to its normal place after its separation from the cord.

Ureterocele is a cystic dilatation of the intravesical ureter that is most commonly observed in females and children, and usually affects the upper moiety of a complete pyeloureteral duplication. According to their position, ureteroceles are divided into intravesical, when the ureterocele is completely contained inside the bladder, and extravesical when part of the cyst extends to the urethra or bladder neck. Most ureteroceles are diagnosed in utero or immediately after birth during an echographic screening of renal malformations. Severe, febrile urinary tract infection is the most common postnatal presentation of ureteroceles, but they may, rarely, prolapse and acutely obstruct the bladder outlet. Once an ureterocele is identified sonographically, a voiding cystourethrogram to detect vesicoureteral reflux (VUR) and a 99m-technetium dimercapto-succinic acid renal scan to evaluate the function of the different portions of the kidney are mandatory. VUR in the lower pole is observed in 50% of cases and in the contralateral kidney in 25%. Simple endoscopic puncture of the ureterocele has recently been advocated as an emergency therapy for infected or obstructing ureteroceles and as an elective therapy for intravesical ureteroceles. The rate of additional surgery after elective endoscopic puncture of an orthotopic ureterocele ranges from 7 to 23%. Treatment of ectopic ureteroceles is more challenging and both endoscopic puncture and upper pole partial nephrectomy frequently require additional surgery at the bladder level. The reoperation rate after endoscopic treatment varies from 48 to 100%. It is 15 to 20% after upper pole partial nephrectomy if VUR was absent before the operation, but is as high as 50-100% when VUR was present. Thus, endoscopic incision is appropriate as an emergency treatment or when dealing with a completely intravesical ureterocele. Upper pole partial nephrectomy is the elective treatment for an ectopic ureterocele without preoperative VUR. In an ectopic ureterocele with VUR, no matter which type of primary therapy has been chosen, a secondary procedure at the bladder level, involving ureterocele removal and reimplantation of the ureter(s), should be anticipated.

Ureteral hernia is uncommon and usually misdiagnosed. From an anatomic point of view, we can distinguish between two uretero-inguinal hernias: intraperitoneal and extraperitoneal. Ureter inguinal hernias are nearly always indirect. This kind of hernia can include the ureter alone or, frequently, other abdominal sliding organs within the hernia sac (bladder, bowel tracts, etc.). Kidneys and urinary tracts present normal anatomic conformation, although renal ptosis may be found. As of July 2004, 139 cases of ureteral hernia had been described in the literature. Here we report a case of inguino-scrotal herniation of double district ureter and review the current literature to analyze the main clinical characteristics of this pathology and to establish pitfalls.

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.

During the past 5000 years, ancient nomenclature and dogmas regarding the etiology of protrusions have accumulated. Whereas, in the abdomen, the Latin "hernia" supplanted Greek, it, based on content, persists in the pelvis as cystocele, rectocele, etc. Russell (Lancet 1:1519-1523, 1902) championed the congenital saccular theory of herniae, denying they could ever be acquired pathologically. Barring technical error, removal of the sac would cure. Despite dissent in the 1920s by Harrison, Keith, and Andrews, Russell's concepts held late into the twentieth century. We now know that pathology - systemic connective tissue disease - plays an important role in adult herniation. Tensionless prosthetic repair is usually required since the healing of damaged musculo-aponeurotic structures in abdomen or pelvis is impaired. Laparoscopists have declared sliding extraperitoneal prolapse of sacless kidney, ureter, bladder, and fat pad to be herniae. Similar vaginal protrusions should be denoted likewise. It is time gynecologists and herniologists join in the effort to develop antidotes for combating this pernicious co-morbidity which has been shown also to cause aneurysms, diverticulosis coli, skin changes, and emphysema. Prophylaxis should include exercise and going without cigarettes.

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.

Although most gynecologists are comfortable performing vaginal hysterectomy in the patient without significant uterovaginal prolapse, vaginal hysterectomy for the prolapsed uterus poses unique challenges and requires an increased awareness of deviations in pelvic anatomy that may result. This review article discusses the background of vaginal hysterectomy performed for uterovaginal prolapse, the pathophysiology of uterovaginal prolapse, preoperative assessment of the patient with uterovaginal prolapse, surgical technique, ureteral anatomy, techniques to avoid injury to the ureter at the time of vaginal hysterectomy for uterovaginal prolapse, and other relevant considerations.
