ABSTRACT
Purpose: The main objective of this multicentric retrospective pilot study was to evaluate the 1-year follow-up safety (i.e., minor [Clavien-Dindo I-II] and major [Clavien-Dindo ≥III] complications) of holmium laser enucleation of the prostate (HoLEP), GreenLight photoselective vaporization of the prostate (GL PVP), and transurethral resection of the prostate (TURP) performed after kidney transplantation (KT). The secondary objectives were to evaluate the efficacy and to assess the impact of these procedures on graft function. Materials and Methods: We retrospectively included all KT recipients who underwent a HoLEP or GL PVP or TURP for benign prostatic hyperplasia (BPH) in three French university centers. Results: From January 2013 to April 2018, 60 BPH endoscopic surgical procedures in KT recipients were performed: 17 HoLEP (HoLEP group), 9 GL PVP (GL PVP group), and 34 TURP (TURP group). Age, body mass index, preoperative serum creatinine, preoperative International Prostatic Symptom Score, preoperative Qmax, preoperative prostate-specific antigen, medical history of acute urinary retention (AUR), urinary tract infection (UTI), and indwelling urethral catheter were similar in all study groups. Mean preoperative prostate volume was higher in HoLEP group. The rate of overall postoperative complications was statistically higher in the HoLEP group (11/17 [64.7%] vs 1/9 [11.1%] vs 12/34 [35.3%] in HoLEP group, GL PVP group, and TURP group, respectively, p = 0.02), with higher rate of long-term UTI and AUR. Qmax improved in all groups after operation. Delta postoperative month 12-preoperative serum creatinine was similar in the all groups. Conclusions: Although our study is underpowered, the rate of postoperative complications is higher with HoLEP procedure, in comparison with GL PVP, for the treatment of BPH after KT. One-year efficacy is similar in HoLEP, GL PVP, and TURP groups. Further prospective randomized controlled trials are needed to confirm our results.
