RESUMEN
We evaluated the feasibility and the benefits of total prostatectomy with suprapubic cystostomy drainage instead of a urethral Foley catheter. Of 65 consecutive total retropubic prostatectomies, 42 were carried out with the suprapubic cystostomy, and 23 with the urethral Foley catheter. Patients were asked postoperatively to complete a 5-cm visual analog scale on pain intensity related to the catheter and to urination after catheter removal. No problem related to cystostomy per se was observed. In the cystostomy group, over 85% and 69% of men perceived no urinary symptoms during catherization and no painful urination after catheter removal, respectively; whereas in the Foley group, 91% and 65% perceived those symptoms (P < 0.001 and P < 0.01, respectively). These findings suggest that urethral catheter-free prostatectomy is a good alternative to that with a urethral Foley catheter, and it gives patients an improved quality of early postoperative life.

BACKGROUND: Neoadjuvant hormone therapy remains a controversial issue in spite of multiple studies having been performed. METHODS: We performed short-term (10 days) treatment with diethylstilbestrol (DES) in 30 patients with stages T2 or T3 prostate cancer (PCa). All the patients underwent needle core prostate biopsy before and radical prostatectomy within a month after the start of the endocrine therapy. The histological effects in PCa and the changes in morphological and clinical parameters and their association were elucidated. RESULTS: Serum PSA (P < 0.001), Ki-67 PI (P = 0.022), and AR (P = 0.002) expression decreased after the treatment. An obvious effect (Grade 1-3) of endocrine treatment was seen in 11 of 30 patients and was associated with a prominent PSA decrease (P = 0.0274) and with older age (P = 0.0026). Pre-treatment specimens from a group without any effects of endocrine therapy had a higher frequency of Bcl-2 positivity (57.9%) compared to the group of Grade 1-3 effects (27.3%). Prostatectomy specimens presented with significantly higher AI in Bcl-2 negative cases (P = 0.0029) and pre treatment Bcl-2 was associated with a higher AI in Grade 1-3 patients (P = 0.0393). CONCLUSIONS: Older age is a predictor of histological effects in short-term hormone treatment of PCa. A lower Bcl-2 in biopsy specimens presented more frequently in the patients who experienced a prominent effect of endocrine therapy, and it was also useful to predict a significantly higher AI in Grade 1-3 patients. Histological effects are also associated with the PSA decrease, reflecting the clinically meaningful shrinkage of tumors and a decrease of tumor burden.
