RESUMO
OBJECTIVE: This study was to explore the risk factors for postoperative bladder neck contracture (BNC) after transurethral operation of prostate in patients with small-volume prostatic obstruction. METHODS: Clinicopathologic data at our center from February 2016 to January 2020 were retrospectively collected and analyzed. Clinicopathological characteristics between patients with and without BNC were compared. Multivariate logistic regression was used to determine the risk factors for postoperative BNC. RESULTS: There were a total of 39 patients (8.53%) with postoperative BNC. Multivariate logistic regression analysis demonstrated that preoperative bladder neck diameter (BND), intravesical prostatic protrusion (IPP), surgical methods (transurethral resection of prostate (TURP)/anatomical endoscopic enucleation of the prostate (AEEP)), and postoperative urinary tract infection (UTI) were independent risk factors for postoperative BNC in patients with small-volume prostatic obstruction (P < 0.05). The incidence of postoperative BNC in patients undergoing AEEP was significantly decreased compared with those undergoing TURP. The optimal cut-off value of preoperative IPP was 6.10 mm while the optimal cut-off value of preoperative BND was 2.52 cm. CONCLUSIONS: Larger preoperative bladder neck and higher preoperative IPP lead to decreased incidence of postoperative BNC in patients with small-volume prostatic obstruction. Active management of postoperative UTI could effectively prevent the occurrence of postoperative BNC. Compared with TURP, complete AEEP would contribute to reduce BNC in patients with small-volume prostatic obstruction.

Transurethral resection of the prostate (TURP) remains the 'gold standard' for surgical treatment of benign prostatic obstruction (BPO). Recently, anatomical endoscopic enucleation of the prostate (AEEP) using holmium laser, thulium laser and plasma, etc., is extensively applied in clinical practice. However, perioperative complications of AEEP are inevitable in spite of lower incidence compared with TURP. This study reviewed the literature related to the aetiology, prevention and treatment of common complications of AEEP, which would contribute to the diagnosis and treatment of BPO.

Background. To investigate the factors associated with the occurrence of and recovery from stress urinary incontinence (SUI) after plasmakinetic enucleation of the prostate (PKEP). Materials and Methods. This retrospective study enrolled 1,288 patients with benign prostatic hyperplasia treated with plasmakinetic enucleation from January 2008 to January 2015, collecting demographics and clinical parameters. SUI was defined as a patient complaint of involuntary urine leak, including stress or mixed urinary incontinence. Logistic regression analysis was used to investigate the factors associated with the occurrence of SUI. Results. SUI after PKEP occurred in 80 of 1,288 patients (6.2%), 73 of whom (91.3%) recovered within 3 months and 78 of whom (97.5%) recovered within 6 months. In multivariate regression analysis of factors that were significant in univariate analysis, the factors that were significantly associated with postoperative SUI were age ≥ 70 years (odds ratio [OR] = 9.239; 95% confidence interval [CI] = 4.616-18.495; P < 0.001) and prostate volume on transrectal ultrasound ≥ 90 mL (OR = 15.390; 95% CI = 8.077-29.326; P < 0.001). Conclusions. SUI occurred in 6.2% patients after PKEP and was associated with older age and larger prostate volume. We suggest that age and prostate volume be considered in preoperative candidate selection before PKEP to reduce the occurrence of postoperative SUI.

OBJECTIVE: To evaluate the efficacy and safety of bipolar transurethral enucleation and resection of the prostate (B-TUERP) versus bipolar transurethral resection of the prostate (B-TURP) in the treatment of prostates larger than 60g. MATERIAL AND METHODS: Clinical data for 270 BPH patients who underwent B-TUERP and 204 patients who underwent B-TURP for BPH from May 2007 to May 2013 at our center were retrospectively analyzed. Outcome measures included operative time, decreased hemoglobin level, total prostate specific antigen (TPSA), International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), quality of life (QoL) score, post void residual urine volume (RUV), bladder irrigation duration, hospital stay, and the weight of resected prostatic tissue. Other measures included perioperative complications including transurethral resection syndrome (TURS), hyponatremia, blood transfusion, bleeding requiring surgery, postoperative acute urinary retention, urine incontinence and urinary sepsis. Patients in both groups were followed for two years. RESULTS: Compared with the B-TURP group, the B-TUERP group had shorter operative time, postoperative bladder irrigation duration and hospital stay, a greater amount of resected prostatic tissue, less postoperative hemoglobin decrease, better postoperative IPSS and Qmax, as well as lower incidences of hyponatremia, urinary sepsis, blood transfusion requirement, urine incontinence and reoperation (P<0.05 for all). CONCLUSIONS: B-TUERP is superior to B-TURP in the management of large volume BPH in terms of efficacy and safety, but this finding needs to be validated in further prospective, randomized, controlled studies.
