The efficacy of transurethral resection of the prostate in the patients with weak bladder contractility index.

OBJECTIVES

We evaluated the effect of transurethral resection of the prostate (TUR-P) in men with weak bladder contractility who were unresponsive to medical treatment.

METHODS

Among the patients who underwent TUR-P for lower urinary tract symptoms at our institution, we reviewed the records of consecutive 71 patients who had preoperative urodynamic evaluations. According to the bladder outlet obstruction index and the bladder contractility index, the patients were divided into 2 groups: group A (25 patients) with unobstructed and weak bladder contractility, and group B (46 patients) with obstructed and/or normal bladder contractility. We investigated the differences of International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Q(max)), postvoid residuals (PVR), and the patient subjective satisfaction between the 2 groups after the TUR-P.

RESULTS

Mean follow-up period after TUR-P was 19 months (range 12 to 55 months). After the TUR-P, the IPSS/QoL, and PVR were significantly improved in group A and all parameters in group B. Patients in group B showed a more significant improvement with regard to the IPSS and they were more satisfied after the TUR-P than group A.

CONCLUSIONS

There were significant improvements in IPSS/QoL and PVR after TUR-P in patients with weak bladder contractility and more than 60% were satisfied with the results of the surgery. TUR-P is considered an optional procedure for the treatment of men with weak bladder contractility who are unresponsive to medical treatment.
