The 7% LR rate after treatment of STS with FSS without RT reported herein is comparable to published rates following treatment where adjuvant RT is used. These results suggest there may be a select subset of patients with STS in whom carefully performed FSS may serve as definitive therapy and in whom adjuvant RT may not be necessary. However, further study is needed to carefully define this subset of patients and to identify the optimal surgical approach and technique for patients treated without RT.

Ureteric obstruction causing renal failure is a serious complication of advanced prostate cancer. Percutaneous nephrostomies (PCNs) are used to decompress the obstructed kidney(s). This study aims to identify whether bilateral PCN insertion confers any advantage over unilateral PCN insertion for patients with bilateral ureteric obstruction. In a cohort of 25 patients, 18 underwent bilateral and 7 underwent unilateral PCN insertion. The mean survival time following PCN was 7.5 months for all patients. The data suggest that the nadir serum creatinine after PCN insertion was similar, independent of whether one or two nephrostomies were inserted. There was also little difference in the serum creatinine levels at the time of death, suggesting that survival after PCN insertion is based on the aggressiveness of the prostate cancer as opposed to the number of nephrostomies inserted.
