Evaluation of a novel technique of bladder neck and supramontanal sparing ejaculatory preserving transurethral prostatectomy.

PURPOSE

Transurethral resection of the prostate (TURP) can achieve highly satisfying symptomatic and functional outcomes but the loss of antegrade ejaculation represents a major reason for the avoidance of surgical treatment to preserve normal ejaculation and paternity. We present a novel technique to duplicate both bladder neck sparing and supramontanal sparing with resection of apical tissues to improve voiding and antegrade ejaculation.

METHODS

A prospective study done from June 2018 to June 2020 on 60 consecutive male patients with normal sexual activity diagnosed with benign prostatic enlargement. These patients were randomized into two groups; 30 patients in each group. Group 1 underwent bladder neck and supramontanal sparing ejaculatory preserving transurethral bipolar resection of prostate (ep-TUBRP) and Group 2 underwent classic transurethral bipolar resection of prostate (c-TUBRP). All patients were evaluated pre- and postoperatively (after 3 months) using IPSS, Qmax and by IIEF-5.

RESULTS

In both groups, there were significant improvements 3 months postoperative in Qmax [7.97 mL/s to 18.47 mL/s (group A) and 7.8 to 20.7 mL/s (group B)] and in micturition symptoms according to reductions in IPSS score [24 to 7.5 (group A) and 25 to 8.5 (group B)]. IIEF-5 score improved significantly from a mean of 12.9 to 18.6 (group A) and from 11.6 to 16.4 (group B). Antegrade ejaculation reported in 80% of patients in group A and 27% in group B which was significant (p < 0.001). Postoperative period did not reveal acute urinary retention, stress urinary incontinence, or serious adverse events.

CONCLUSIONS

On short-term results, bladder neck and supramontanal ejaculation preserving transurethral bipolar resection of the prostate is superior to classic TURP in preservation of forward ejaculation with comparable efficacy in micturition parameters.
