RESUMEN
OBJECTIVE: To investigate the perioperative parameters and postoperative sexual function and complications in native Tibetans undergoing transurethral resection of the prostate (TURP) for BPH with different prostate volumes. METHODS: From June 2015 to February 2017, 325 native Tibetans with BPH underwent TURP in the People's Hospital of Tibet Autonomous Region. The patients were aged 59ï¼88 years, with a median oxygen saturation level of 84% in the normal status, 24% with hydronephrosis, 40.3% with the history of acute urinary retention, 61.8% with pulmonary hypertension, and 19.1% taking regular medication preoperatively. According to the preoperative prostate volume (PV), the patients were divided into a large PV (LPV) group (PV ≥80 ml, n = 124) and a small PV (SPV) group (<80 ml, n = 201). Perioperative parameters and postoperative sexual function and complications were analyzed and compared between the two groups of patients. RESULTS: The operation time was significantly longer in the LPV than in the SPV group (ï¼»92.36 ± 26.35ï¼½ vs ï¼»56.28 ± 24.61ï¼½ min, P < 0.05) and the intraoperative blood loss was higher in the former than in the latter (ï¼»401.12 ± 50.12ï¼½ vs ï¼»385.15 ± 51.62ï¼½ ml, P < 0.05). Compared with the baseline, at 6 months after operation, the IPSS was significantly decreased in all the patients (22.13 ± 6.23 vs 5.29 ± 1.14 in the LPV group, P < 0.05; 23.04 ± 6.82 vs 5.12 ± 1.28 in the SPV group, P < 0.05), and the maximum urinary flow rate (Qmax) remarkably improved (ï¼»17.46 ± 5.82ï¼½ vs ï¼»5.91 ± 1.86ï¼½ ml/s in the LPV group, P < 0.05; ï¼»17.99 ± 5.86ï¼½ vs ï¼»6.01 ± 1.92ï¼½ ml/s in the SPV group, P < 0.05). The incidence rate of retrograde ejaculation was markedly higher in the LPV than in the SPV group postoperatively (48.4% vs 20.9%, P < 0.05). No statistically significant differences were observed between the two groups of patients in the incidence of postoperative complications (13.71% vs 9.45%, P > 0.05). CONCLUSIONS: TURP is effective and safe for the treatment of BPH native Tibetans with different prostate volumes.
