Factors Affecting the Morbidity after Transurethral Prostatectomy for Benign Prostatic Hyperplasia / 대한비뇨기과학회지

ABSTRACT

Medical records of 570 patients underwent transurethral prostatectomy from 1985 to 1991 were reviewed to analyze the factors affected morbidity after transurethral prostatectomy retrospectively. Transurethral prostatectomy constituted 16.9% of the urologic operation during above periods and there were benign disease in 513 patients(90%), and carcinoma in 57 patients(10%). Age of the patients ranged from 48 to 93 years old with a mean age of 68.3. Of the patients, 298 patients (52.3%) had significant pre-existing medical problems. The resected net tissue weight ranged from 3 to 73 grams, with a mean of 11.8 grams. The mean operation time was 53 minutes with a range from 25 minutes to 126 minutes. The mortality was 0.36% and the operative morbidity was 20.3%. Increased morbidity was found in patients with a resection time of more than 90 minutes, used glycine of more than 20,000ml and resected weight of more than 31 grams (P<0.05) But age greater than 80 years, azotemia, urinary tract infection, serum Na+ change and pre-existing disease did not increased the operative morbidity. Voiding symptom was improved in 551 patients(96.7%) but in 19 patients(3.3%). persistent voiding difficulty was found. postoperatively at three months The causes of voiding difficulty were as follows ; 10 incontinence patients, 8 detrusor areflexia patients and 1 urethral stricture patient. In conclusion, transurethral prostatectomy is one of the most common operations today with a very low mortality and the overall postoperative results are excellent. Further studies, such as a randomized trial, will be necessary to evaluate the long-term outcome of transurethral prostatectomy further.
