A patient with a tumor in the right pelvic ureter is described herein. Following diagnosis by ureteroscopy, the patient underwent TUR utilizing a ureteroresectoscope. No short- or long-term complications were observed. The scant number of cases in the literature and the advantages afforded by this technique (noninvasive, short duration of hospital stay, etc.) prompted us to report this case.

The statistics of urological operations performed at our department between Jan., 1, 1982 and Dec., 31, 1986 were reviewed. During the 5 year period, 2331 patients were admitted to our hospital and 2192 urological operations were performed on 1834 patients. These statistics were compared with earlier statistics for two periods (1972-1976 and 1977-1981) and the recent trend of urological operations was investigated. With regard to operated organ, operations on the kidney were the most frequent followed by those on the urinary bladder. Operations on the ureter decreased during the recent 5 year period and they were the fourth most frequent following those on the scrotum, scrotal contents and penis. Operations on the adrenal gland, retroperitoneal space and parathyroid gland have gradually increased. As in the former report, transurethral resection of bladder tumor (TUR-Bt) was the most frequent and nephrectomy, TUR of prostate (TUR-P) and renal allotransplantation have followed. TUR-Bt and TUR-P have increased more and more and due to the introduction of percutaneous nephrolithotripsy and transureteral lithotripsy, open surgery for urolithiasis has greatly decreased. Endourological operations will still be on the increase.

Statistical observations of 19,678 outpatients and 2,601 inpatients at our department from 1975 to 1982 revealed the following results. The new cases in the outpatient clinic were in decreasing order nonspecific infections (50.8%), urogenital tumors (11.9%), urolithiasis (9.3%) and urogenital anomalies (8.0%). The inpatients according to the organ were in decreasing order kidney (29.6%), prostate (25.5%), bladder (13.4%) and ureter (11.9%). Operations were performed 2,414 times. Frequent operations were in decreasing order phimosectomy (360 times, 14.9%), TUR-Bt (284 times, 11.8%), transurethral cryosurgery of the prostate (215 times, 8.9%), vasectomy (190 times, 7.9%) and orchiopexy (152 times, 6.3%). More young persons comprised the outpatients of our hospital than at other facilities.

Condylomata in the urethra usually occur as a complication to genital warts on the external genitals and are most often situated in the distal part of the urethra. This is a report of a male patient with recurring papillomatous transitional cell tumors, stage Ta and T1, grade 2 and 3 in the bladder and the right ureter, who presented with extensive condylomatosis in the urethra from the meatus to the verumontanum, without simultaneous presence of condylomata at the external genitals. Condylomatous fragments were also present in the TUR specimen from the bladder, but may have been displaced from the urethra during cystoscopy. Using PCR technique and in situ hybridisation, HPV types 6/11 were detected in the condylomata, but no virus was present in the transitional cell tumors.

A 79-year-old woman was admitted with recurrent ureteral and bladder cancers. She had a horseshoe kidney with a non-functioning right renal unit. Fifteen months earlier, multiple urothelial tumors had first developed in the left upper ureter and bladder. Transurethral resection of bladder tumor (TUR-Bt) and partial ureterectomy (2 cm) had been performed. Presently, the recurrent tumors were located at the left lower ureter and bladder. Considering the high age of the patient, TUR-Bt and partial ureterectomy (5 cm) were performed. Besides urothelial cancers, she had been operated for carcinomas of the colon, uterus and stomach. Kidney-sparing therapy has successfully maintained her quality of life.

The authors present the results of different operative treatments of tumors of the upper urinary tracts (UUT). A total of 116 patients with UUT tumors were examined and treated from 1990 to 2002 (age 19-80 years, mean age 61.3+/- 1.3 years; males 82, females 34). Tumors of the renal pelvis and the ureter were detected in 76 (65.5%) and 40 (34.5%) patients, respectively (8.0 and 4.3% of a total number of patients with tumors of the kidneys and UUT). 107 (92.2%) patients were operated. Nephroureterectomy and ureterectomy with resection of the urinary bladder were performed in 73 (68.2%) patients, TUR of the urinary bladder wall, ureteral ostium with pelvic part of the ureter and nephroureterectomy (including endovideosurgery) in 22 (20.6%), nephroureterocystectomy in 4 (3.7%), resection of the pelvic ureter with Boari's operation in 5 (4.7%), nephroscopy, ureteroscopy with removal of urothelial tumor in 3 (2.8%) patients. Postoperative complications (most of them infectious-inflammatory) developed in 10 (9.3%) patients. Lethality was 0.9%. Tumor recurrences occurred in 27 (25.2%) patients within 5-year follow-up. 15 (14.0%) patients were reoperated. 5-year survival reached 67.0%. Conventional and radical method of treating patients with tumors of the renal pelvis and ureter is nephroureterectomy with urinary bladder resection and its modification. In invasion of the tumor in the muscular layer of the bladder wall surgery should be extended and supplemented with cystectomy. Conservative surgical interventions are indicated in tumors of the sole kidney, bilateral process, benign or surface tumor of the urothelium.

A 73-year-old woman complained of gross hematuria. Urine cytology showed small cell carcinoma (SmCC) cells mixed with urothelial carcinoma (UC) cells. Cystoscopy revealed a bladder tumor around the right ureteral orifice. Abdominal CT demonstrated severe right hydronephrosis. Pelvic MRI showed a mass (approximately phi5 cm) in the urinary bladder wall that protruded into the lumen. TUR biopsy of the bladder tumor was SmCC. With laparoscopic nephrectomy/open ureterectomy, distal end (approximately 10 cm) of the right ureter was tumorous and obstructed. The tumor invaded into the urinary bladder/peritoneum and was unresectable. The tumor of lower-end of ureter tumor was SmCC, showing neuroendocrine differentiation such as pseudo-rosette, positive Grimelius stain, and chromogranin A/NCAM/synaptophysin immunostaining. Proximal to this tumor, non-invasive UC spread superficially over entire length of the ureter to the renal pelvis. Abrupt transition from invasive SmCC to non-invasive UC was observed in the middle of the ureter. Post-operative adjuvant chemotherapy was discouraged due to senile dementia of the patient. The patient died nine months after the operation because of systemic progression of cancer.

A 70-year-old man with previous history of TUR-BT presented positive urinary cytology at one year follow-up. Cystoscopy with bladder mapping was negative, and IVP revealed multiple outpouchings of the right upper ureter without hydronephrosis. Ureteroscopy failed because of an underlying stricture. Surgical excision of the strictured segment and of 2.5 cm of cranial ureter was performed. Histopathology demonstrated focal hyperplasia of the urothelium with outpouchings involving only the mucosa, compatible with the diagnosis of pseudodiverticula.

A 58-year-old man visited our hospital with a complaint of asymptomatic gross hematuria for three weeks. The urine cytology at another clinic had indicated Papanicolaou class V. A physical examination revealed soft abdominal distention in lower abdomen. Ultrasonography demonstrated an extremely dilated left pelvis, calyx and ureter in which a round mass was detected. Enhancement CT showed a mass 2 cm in diameter in the middle part of the dilated left ureter. These findings suggested the diagnosis of left ureteral cancer having developed in the megaureter. Neither VUR nor UVJ stenosis were identified by VCG and RP. MR-urography showed a severely dilated left pelvis and tortuous megaureter. On the diagnosis of left ureteral cancer left nephroureterectomy with cuff of bladder was performed. Gross findings showed a 2 cm sized papillary tumor in the extremely dilated ureter, and pathological findings showed grade 2, papillary transitional cell carcinoma and non-specific ureteritis in the dilated ureter. Postoperative course was non-eventful. Postoperative 3 months later multiple bladder tumors were detected all over the bladder, and so TUR-Bt and intravesical instillation therapy with pirarubisin was performed. However multiple bladder tumors had been relapsed and so finally radical cystectomy and right cutaneous ureterostomy were undergone postoperative 6 months later. He has been well 48 months postoperatively.
