RESUMO
PURPOSE: Cases of ureteroscopic lithotripsy (URS) were retrospectively reviewed to define the efficacy of an ureteroscopic lithotripsy in the treatment of upper ureteral stones. The success rates, reasons for failure and complications of URS were compared with extracoporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS: URS for upper ureteral stones was performed in 48 cases, between January, 2000 and December, 2002. A 7.5Fr, or 9.5Fr, rigid ureteroscopy and stone basket were used with, or without, electrohydraulic lithotripsy. There were 29 males and 19 females, with a mean age of 43.3 years. RESULTS: The overall success rate of the URS was 91.6%. According to the stone size, the success rates were 92.1 and 90% in stones smaller than 10mm and larger than 10mm, respectively. With the ESWL treatments, the overall stone free rate was 71.7% with only one session. The stone free rate was significantly affected by the size, was and were 77.9 and 46.3% in stones smaller than 10mm and larger than 10mm, respectively. The stone free rate after the second and third ESWL sessions were 81.3 and 91.3%, respectively. The associated complication rate for URS was 18.1%, with the complications consisting of ureteral mucosal injuries in 3 patient, flank pain (>48 hours) in 2, a ureteral perforation in 1, fever in 1 and a gross hematuria (>48 hours) in 1, which were all treated successfully with conservative treatment. CONCLUSIONS: URS can be a successful and safe treatment modality for upper ureteral stones, even if larger than 10mm.

Ureteral tumors are relatively uncommon, accounting for approximately 1.2% of all urothelial tumors. Metastatic ureteral tumors are even rarer. The primary lesions include breast, melanomas, bladder, colon, stomach, lung, and esophageal, prostate, ovarian, kidney, urethral and vaginal carcinomas. Patients usually have lumbar or flank pain, dysuria, frequency, and in the latter stages, anuria. We report a case of a metastatic ureteral tumor from a lung squamous cell carcinoma after complete remission.

Retroperitoneal fibrosis, although benign, has a malignant course due to an encasement and obstruction of the retroperitoneal structures, particularly the urinary system. The most common treatment is often a surgical exploration followed by urologic intervention. However, steroid or azathioprine therapy has been advocated, with varying results and major side-effects. Recently, the successful medical therapy in patients with an early stage and low malignant potential has been reported. Here we report a male patient who underwent successful treatment of an idiopathic retroperitoneal fibrosis with tamoxifen and prednisolone.

Priapism is a relatively rare condition of prolonged painful penile erection, unrelated to sexual activity. It is caused by idiopathic, leukemia, sickle cell disease, oral medication, intracavernosal injection therapy, spinal cord injury and malignant cell infiltration. Malignant lymphoma involving the genitourinary system is uncommon and when it occurs the testes is the most common site. However malignant lymphoma involving the penis is even more rare, with only 20 cases reported in literature. To our knowledge, priapism caused by penile lymphoma has not been reported previously in literature. We report a case with a brief review of literature.
