“…In all cases, we used the same size (22.5F) laser cystoscope, thus, we did not have comparative information in terms of instrument diameters. Although increasing endoscope size is a risk factor for stricture in transurethral procedures, Kiba et al showed more frequent US after PVP in comparison to bipolar enucleation of the prostate (16% vs 0%) where a smaller-size instrument was used for PVP, suggesting that urethral stricture can arise from various causes [ 18 ]. Studies have priorly suggested an association between the presence of infections, increased prostate volume, repeated urethral catheterizations, and the risk of developing sclerotic changes in the urethra following all transurethral surgeries.…”

Objective To assess the incidence, risk factors, and timing of specific causes of reoperations following PVP. Material and Methods A retrospective analysis of data on men who underwent GreenLight PVP between 2004 and 2019 in a single center and required surgical intervention for bladder neck contracture (BNC), urethral stricture (US), or persistent/recurrent prostate adenoma. Results The overall rate of reoperations was 13.8% during a 61-month median follow-up of 377 patients. Reoperations were due to BNC, US, and adenoma in 7.7%, 5.6%, and 4.8% of cases, respectively. The median interval until reoperation for US (11 months) was significantly shorter. None of the risk factors had any relevance to US. In patients who underwent reoperation for BNC, lasing time and energy were significantly lower, and the prostate volume was smaller; however, the multivariate analysis only identified shorter lasing time as a predictor. In patients who had reoperation for persistent/recurrent adenoma, the PSA was increased, while the prostate volume was non-significantly high, and performance by less-experienced surgeons was associated with a higher rate of reoperations ( p < 0.05). A longer lasing time predicted an increased risk of reoperation for adenoma in multivariate analysis. Conclusions An unselective utilization of PVP may result in a relatively high rate of reoperations. The correlation of BNC with shorter lasing time may imply a higher risk after PVP of smaller prostates. A longer lasing time predicts an increased risk of reoperation due to persistent/recurrent adenoma, which may be related to higher prostate volumes and inefficient PVP by less-experienced surgeons.
