Pyuria and Post-Operation Urinary Tract Infection after Diode Laser Vaporesection of the Prostate
Background: Monopolar transurethral resection of prostate (m-TURP) remains the gold standard for benign prostate obstruction (BPO). Recently developed laser surgical technique provides fewer peri-operative complications with equivalent outcomes. Diode laser vaporesection (DiLRP) offers better hemostasis, shorter catheterization duration, and shorter hospital stay, however, deep thermal penetration might cause prolonged prostatic urethra inflammation and subsequent complications. We conducted a retrospective study to compare the pyuria duration and post-operative urinary tract infection sequelae (POUTIs) between DiLRP and m-TURP. Methods: From July 2011 to September 2015, we retrieved medical records for patients with lower urinary tract symptoms resulting from prostate obstruction who underwent m-TURP and DiLRP. Demographic characteristics were recorded from a computerized database. The duration of pyuria after operation was compared by Kaplan-Meier analysis and risk factors were evaluated by Cox regression analysis. Results: One hundred twelve patients underwent DiLRP and 81 underwent m-TURP performed by the same surgeon during the same period. The mean age of the patients was 72 ± 7.3 years in the DiLRP group and 70 ± 7.6 years in the m-TURP group (p = 0.069). There was a higher percentage of anticoagulant used in the DiLRP group than in the m-TURP group (18.5% vs. 7.4%, p = 0.028). Operation time was longer but post-operative normal saline irrigation interval was shorter in DiLRP compared with m-TURP, respectively (62.8 ± 20.6 vs. 47.4 ± 22.1 minutes, p < 0.001; 2.1 ± 0.3 vs. 2.5 ± 0.9 days, p < 0.001). The post-operative infections were statistically significantly higher in the DiLRP group, including epididymitis (10.2% vs. 1.2%, p = 0.013) and POUTIs-related hospitalization (8.3% vs. 1.2%, p=0.031).The DiLRP resulted in longer pyuria period (16 vs. 12 weeks, p = 0.0014), with factors including operative method by DiLRP (hazard ratio [HR]: 1.828, p = 0.003) and age (HR: 0.665, p = 0.040). Conclusions: According to our study, DiLRP associated with more POUTIs is possibly caused by a longer pyuria period. Further larger prospective studies are necessary for the evaluation of the association between post-operative pyuria and POUTIs.
