Hemiresection of the prostate: Short-term randomized comparison with standard transurethral resection

Background and Purpose: During transurethral resection of the prostate (TURP) for a very large and vascular gland in a medically compromised patient, there may arise the need for quick termination of the procedure because of medical problems that develop as a result of fluid absorption or bleeding if the surgery is prolonged. In such a situation, an alternative solution proposed by us is termination of the procedure after complete resection of one lateral lobe (and the median lobe, if present) of the prostate (hemiresection). Patients and Methods: From January 1998 to December 2001, 161 consecutive symptomatic men with prostates >50 cc and an indication for prostatectomy were randomized to receive either a standard TURP (group 1; 80 patients) or prostatic hemiresection; i.e., complete resection of one lateral lobe and the median lobe, if present (group 2; 81 patients). The two groups were comparable in terms of age and prostate size. Preoperative and postoperative parameters were compared in the two groups using Student's t-test. Results: Resected tissue weight was significantly greater in group 1, while the resection time and operative blood loss were significantly lower in group 2. The two groups had comparable improvement in symptom score and flow rate. Conclusions: Hemiresection of the prostate produces short-term functional results comparable to those of standard TURP in patients with prostates >50 cc, with shorter operative duration and significantly less bleeding. It is an acceptable surgical option in medically compromised patients with significant cardiac, pulmonary, or renal comorbidity.
