Abstract

Purpose: We assessed the effects of prostate size on long-term health related quality of life and functional outcomes after laparoscopic radical prostatectomy. Materials and Methods: A total of 729 consecutive patients who underwent laparoscopic radical prostatectomy for localized prostate cancer were stratified by pathological prostate gland weight, including group 1-less than 35 gm, group 2-35 to 70 gm and group 3-greater than 70 gm. Urinary health related quality of life was assessed preoperatively and at regular intervals following laparoscopic radical prostatectomy using the validated Expanded Prostate Cancer Index Composite questionnaire. Results: A total of 613 evaluable patients were studied with a mean age of 57.7 years, a preoperative prostate specific antigen of 6.0 ng/ml, a median preoperative and postoperative Gleason score of 6, and a mean pathological gland weight of 51.3 gm (range 13.4 to 145.7). Patients with the largest glands had significantly worse baseline urinary function, as demonstrated by Expanded Prostate Cancer Index Composite urinary domain summary (p <0.001) and subscale scores, including scores for urinary bother (p <0.001), urinary irritative/obstructive (p = 0.001) and urinary incontinence (p = 0.03). Patients in group 3 also had significantly older age, a higher body mass index, longer operative time and more blood loss (each p <0.05). Despite preoperative differences and possible confounders all groups approached similar urinary health related quality of life outcomes at all time points postoperatively. At 12 months patients with the largest glands had improved Expanded Prostate Cancer Index Composite urinary irritative/obstructive and urinary bother subscale scores compared to their baseline scores (p <0.05). Conclusions: In laparoscopic radical prostatectomy despite preoperative differences increasing prostatic size is not associated with delayed or worse postoperative urinary health related quality of life. Furthermore, in patients with large glands an improvement in urinary irritative/obstructive and bother symptoms from baseline may be seen 12 months postoperatively.
