Factors affecting change in quality of life after prostatectomy for benign prostatic hypertrophy: the impact of surgical techniques.
OBJECTIVE
The impact of prostatectomy on quality of life was assessed in patients with benign prostatic hypertrophy (BPH) who were classified according to the expected benefit from surgical intervention. The relative impact of the 2 surgical techniques (open versus closed) on short-term quality of life was compared.


METHODS
An observational study was done on 545 consecutive patients with BPH undergoing prostatectomy at 3 medical centers in Israel between 1991 and 1992. Repeated structured interviews preoperatively, and at 4 and 12 months postoperatively were performed, including 6 quality of life questionnaires evaluating BPH specific (symptom severity and symptom effect) and generic (activity, independence, mental health and health perception) parameters. In addition, the interviews consisted of socio-demographic data elements. Clinical details regarding severity of prostatic disease and co-morbidity were obtained from the medical charts.


RESULTS
We found a correlation between postoperative change in symptom effect and in generic quality of life measures (r-0.11 to 0.20, p < 0.04). The postoperative decrease in the mean symptom effect score was 56% and 52% for severe and moderate preoperative levels, respectively. There was no decrease in the mean symptom effect score for the mild preoperative level (18% of these patients had postoperative deterioration). A secondary operation, and the combination of diabetes mellitus and poor activity level were risk factors for lack of improvement in patients with moderate preoperative symptom effects. We found that the impact of open prostatectomy on quality of life was similar to that of the closed technique after adjustment for patient attributes, except for those with an indwelling urinary catheter in whom an open operation was advantageous.


CONCLUSIONS
In patients with BPH and mild symptom effects, and in subgroups of patients with moderate symptom effects surgery should not be recommended. Based on short-term measures of quality of life there is no justification for a preference between open and closed operations.
