[Transurethral holmium laser enucleation of the prostate for benign prostatic hyperplasia in patients with a history of transrectal prostate biopsy].

Objective: To evaluate the efficiency and safety of transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of BPH in patients with a history of transrectal prostate biopsy (TRPB).

Methods: We retrospectively analyzed the clinical data on 102 cases of BPH treated by HoLEP in our hospital between November 2015 and May 2017, of which 42 had received TRPB prior to HoLEP (the PB group) but not the other 60 (the non-TRPB ［NPB］ group). We compared the preoperative, perioperative and postoperative follow-up data between the two groups of patients.

Results: There were no statistically significant differences in the mean age, prostate volume, and preoperative post-void residual urine volume (PVR), IPSS, quality of life (QOL) score and maximum urinary flow rate (Qmax) between the two groups of patients. The preoperative PSA level was significantly higher in the PB than in the NPB group (［10.30 ± 3.62］ vs ［2.62 ± 1.75］ μg/L, P < 0.01), and the operation time markedly longer in the former than in the latter (［78.00 ± 18.25］ vs ［67.93 ± 15.89］ min, P < 0.01), particularly in the patients with an interval of <2 weeks between HoLEP and TRPB than in those with an interval of ≥2 weeks (［91.17 ± 16.51］ vs ［68.13 ± 12.45］ min, P < 0.01). Statistically significant differences were not found in the postoperative hemoglobin level, continuous bladder irrigation duration, catheter-indwelling time and hospital stay, nor in the incidence rate of transient urinary incontinence between the PB and NPB groups (47.62% vs 45%, P = 0.794). There were no transurethral resection syndrome, bladder or rectal injury, or blood transfusion in either group, nor statistically significant differences in PVR, Qmax, IPSS and QOL score between the two groups of patients at 3, 6 or 12 months after operation.

Conclusions: HoLEP is a safe and effective surgical treatment of BPH for patients with a history of TRPB, which can reduce the time and increase the safety of operation when performed at ≥2 weeks after TRPB.
