[The comparative analysis of surgical procedures a in patients with benign prostatic hyperplasia and type 2 diabetes mellitus].

Aim: To compare the efficiency of two surgical methods, holmium laser enucleation of prostate (HoLEP) and laparoscopic retropubic simple prostatectomy with clamping of internal iliac arteries and vesicourethral anastomosis [LPA+CIIA+VUA]) for treating of patients with benign prostatic hyperplasia (BPH) and type 2 diabetes mellitus (T2DM).

Materials And Methods: A total of 56 men with T2DM who underwent surgical treatment of BPH in the National Research Centre for Endocrinology of the Russian Ministry of Health (director - corresponding member of RAS Mokrysheva N.G..) in a period from 2021 until 2022 were included in the study. Patients with T2DM received two types of antidiabetic drugs: basal-bolus insulin therapy and metformin (1000 mg/day per os). Patients were divided into the group of LPA+CIIA+VUA (n=28) and HoLEP (n=28). Preoperative, intraoperative and postoperative examinations with an evaluation of intraoperative and early postoperative complications (I, II, III, IV grades according to the Clavien-Dindo scale) were performed. After 1 year of follow-up, International Prostatic Symptom Score (IPSS), "Quality of Life" score (QoL), International Index of Erectile Function-5 score (IIEF-5), maximal urine flow rate (Qmax), and postvoid residual volume (ml) were assessed. Efficiency of surgical procedures was estimated according to "trifecta": absence of postoperative complications, urine continence, maximal urine flow (Qmax) >15 ml/sec.

Results: In the group of HoLEP, shorter postoperative bladder catheterization time but higher risk of urinary incontinence, bladder neck contracture and urethral strictures was found. LPA+CIIA+UVA leaded to a two-fold decrease in intraoperative hemoglobin loss with no necessity of repeat procedures.

Conclusions: Our preliminary results demonstrated higher efficacy of LPA+CIIA+VUA for treatment of BPH in patients with T2DM than HoLEP. Patients who underwent LPA+CIIA+VUA were more often achieved the "trifecta". In order to implement LPA+CIIA+VUA into clinical practice, multi-center, large-scale, double-blind, placebo-controlled ("scar-surgery") randomized studies are required.
