[Clinical evaluation of surgical treatment for benign prostatic hypertrophy]

Prostatectomy was performed on 300 patients at our Hospital for the period of 5 years from January 1978 to December 1982. Among those cases, clinical evaluation was made on 290 patients whose medical records were available. Ages of the subjects ranged from 53 to 92 years with an average age at 71.6. Retropubic prostatectomy (RPP) was performed on 81 cases, and suprapubic prostatectomy (SPP) and transurethral resection of prostate (TUR) on 39 and 170 cases, respectively. Surgery was made on 206 cases under epidural anesthesia, 82 cases under spinal anesthesia, and 2 cases under general anesthesia. Preoperative laboratory tests showed abnormalities in 62% of the total. The most frequent preoperative complications were circulatory abnormality and urinary tract infection. Average surgical time was 78.6 min. for RPP, 69.8 min. for SPP, and 76.9 min. for TUR. Average blood volume transfused during operation was 446.3 ml for RPP, 430.8 ml for SPP, and 80.7 ml for TUR. Average period of catheter retention after surgery was 9.2 days for RPP, 10.1 days for SPP, and 4.9 days for TUR. Average postoperative admission period was 18.6 days for RPP, 20.6 days for SPP, and 14.1 days for TUR. Average weight of the isolated adenoma was 41.8 g for RPP, 30.2 g for SPP, 11.5 g for TUR. Postoperative complications such as epididymitis, traumatic infection, and hepatic dysfunction were often found. Latent prostatic carcinoma found in the isolated adenoma was found in 11 cases (3.8%). The presence of anomalies in preoperative laboratory findings did not influence the frequency of postoperative complications.
