It is reported on a septennial observation of a 43 year old woman, who was admitted to the hospital in 1968 with at first unclear symptoms and who developed an azotemia within a few days. The infusion pyelogram showed a hydronephrosis with enlargement of the upper part of the ureter; the lower part of the ureter was normal. After displacement of the ureters out of the fibrotic clasping into a duplicate of the peritoneum, the urine flow has normalized. After 7 years the patient is now healthy and able to work. The cause of the urinary stasis was histologically cleared as retroperitoneal fibrosis.

Neoplastic and non-neoplastic tissues from the urinary tract and the prostate were analyzed for the presence of human papillomavirus (HPV) DNA. The analysis was performed by PCR using primers specific for HPV 6/11 and 16. HPV DNA was present in bladder, ureter, kidney and prostate, with percentages ranging between 46% and 87%. Benign and oncogenic HPV types were detected with similar frequencies both in non-neoplastic and in neoplastic biopsies, and HPV 16 was not preferentially associated with malignant lesions. In all instances, small amounts of HPV DNA were present in the tissues, suggesting the absence of productive infection. Analysis of the physical state of HPV DNA performed by 2-dimensional gel electrophoresis and Southern blot hybridization revealed that HPV 16 DNA harbored in the urinary tract can be integrated also in non-neoplastic tissues. The results indicate that HPV 16 does not seem to be associated with urinary-tract and prostate oncogenesis, but that these tissues may represent an important reservoir for the transmission of HPV types normally infecting the genital tract.

Ureteral injury is a recognized complication of gynecologic surgery. During operative laparoscopy performed to treat extensive endometriosis of the pelvic sidewall, a 1.5-cm portion of the right ureter was resected and was repaired successfully. Repair of a resected ureter may be effectively accomplished endoscopically by experienced operative laparoscopists.

As documented with results obtained in 1685 patients the treatment of ureteric stones is today based on ESWL in situ and ureteroscopy with semirigid, ultrathin ureteroscopes and laser lithotripsy. All stones in the upper third of the ureter and larger stones in the distal third of the ureter are preferably treated with ESWL in situ whereas smaller stones in the distal ureter are better treated endoscopically. Midureteric stones remain the domain of primary ureteroscopy; with moderate obstruction in the asymptomatic patient it may also be acceptable to wait for the stone to pass into the distal ureter spontaneously to be treated by ESWL in situ there. Manipulating stones back into the kidney and treating them by ESWL there (pushback/ESWL) offers no advantage over ESWL in situ, as the results are similar, yet morbidity is higher. Blind instrumentation and open surgery have lost all justification.

A rare case of squamous cell carcinoma of the right kidney associated with giant hydronephrosis and right ureteral stone was reported. A 60-year-old woman was referred to our department with a complaint of ileocecal dull pain. A plain computerized tomogram (CT) revealed giant hydronephrosis, and a kidney-ureter-bladder X-ray revealed a right lower ureteral stone. A right percutaneous nephrostomy was done and antegrade pyelography revealed giant hydronephrosis and a ureteral stone, but showed no intrapelvic filling defect. Under the diagnosis of right ureteral stone with hydronephrosis, right ureterolithotomy was done. However, since the inflammation did not subside after ureterolithotomy, right nephrectomy was done. The surgically removed right kidney did not show any evident tumor mass, a histological study revealed squamous cell carcinoma involving renal parenchyma. The patient received no adjuvant therapy and died 3 months after nephrectomy with sudden appearance of bone, liver and pulmonary metastases. The preoperative efficacy of imaging modalities for renal squamous cell carcinoma was discussed herein.

Development of complications of the pelvis and the ureter, especially obstruction and necrosis with an urinary fistula was seen in 35 of 751 patients after kidney transplantation (4.6%). In this study they occurred significantly often in patients with multiple renal arteries of the donor kidney, for example pole arteries. An arterial angiography of the aorta abdominalis in living donors before transplantation is not be neglected. The diagnosis of urological complications includes sonography, in cases of ureteral obstruction percutaneous antegrade urography, and in a given case computed tomography.

Urological complications were studied in 310 live donor kidney transplants. All recipients and donors were investigated for urinary schistosomiasis by examining tissue obtained intra-operatively from the donor's ureter or the patient's bladder. Schistosomiasis was histologically documented in 76 cases (patient's bladder (46), donor's ureter (9), both (21)). The incidence of urological complications was 11/76 (15%) in the schistosomal group and 14/234 (6%) in the non-schistosomal group; this was statistically significant. Among the schistosomal patients, the site of infestation had no statistically significant effect on the incidence of urological complications. No deaths or graft losses were directly attributable either to these complications or to their surgical correction.

The chapter of injuries to the ureter during obstetric-gynaecological surgery continues to be ignored in the literature published over the last decades, in spite of its prevalence in the practice. This has motivated our review and update of this issue. The interest of urological diagnostic procedures prior to surgery and conduit examination at any time during the operation exert some influence on the prevention of this pathology. Preoperative finding and reconstruction lead to better results, which benefit from the use of the urinary route, thus leaving the gut route and self-transplantation for exceptional situations. A new iatrogenic pathology has emerged from the most frequent use of gynaecological endoscopic surgery.

In 282 patients 290 ureteral stones were treated with extracorporeal shock wave lithotripsy using the Lithostar lithotriptor. Stones were in the upper ureter in 198 units (68.3%), middle ureter in 36 (12.4%) and lower ureter in 56 (19.3%). The average stone mass was 11.9 mm. and the mean number of shock waves was 4,913 for all levels with a mean kv. of 16.9. The average number of sessions was 1.5 for all sites. Auxiliary measures in the form of ureteral catheterization were done in 24 patients (8.5%) and internal stenting in 12 (4.25%), all of whom had upper or middle ureteral stones. Disintegration of the stones was achieved in 99% of the upper, 93.7% of the middle and 91.7% of the lower ureteral stones. However, clearance of fragments within 3 months from the last session was achieved in 94.8% of the upper, 87.5% of the middle and 91.7% of the lower ureteral stones for an overall stone-free rate of 93.3%.

Within the wide armamentarium of urinary stone treatment modalities extracorporeal shock wave lithotripsy (ESWL) has been established as the first line procedure. With the Dornier MPL-9000X lithotriptor one has the choice of ultrasound or fluoroscopic localization of calculi throughout the entire urinary tract. Except for the kidney, ultrasound guidance is preferred for calculi in the distal ureter, while fluoroscopy is generally used on the proximal two-thirds of the ureter. Between January and December 1990, 123 ESWL treatments were performed on 83 patients suffering from ureteral calculi with an average stone size of 9.3 x 6 mm. Median treatment parameters were 1,597 shock waves at 19.3 kv. for 43 minutes. For stones in the upper two-thirds of the ureter sedation analgesia was given, while ESWL on the pelvic ureter did not create intolerable pain. Of the treatments 69% were done on an outpatient basis. In situ ESWL treatment of urinary calculi was successful in 72 patients (86.7%), and 20 patients (24.1%) were treated with multiple treatment sessions. ESWL therapy for 47 stones in the distal ureter showed better results than for 33 stones plus 2 steinstrasse in the proximal part (95.5% versus 80% stone-free rate). Of 4 patients with mid ureteral calculi 2 could be rendered stone-free by ESWL alone. Auxiliary procedures, such as percutaneous nephrostomy or ureteral splints, had to be performed in 15.7%. Final endoscopic stone extraction was done in 7 cases and open surgery in 4, constituting a 13.3% failure rate for ESWL therapy. The results prove that the MPL-9000X lithotriptor is effective for primary noninvasive stone treatment.
