“…Although the etiology of urethral stricture after endoscopic urethral surgeries remains unclear, patientrelated factors, iatrogenic traumas developing during the surgery, and infections are the most frequently implicated factors. In addition, there are limited data in the literature suggesting that prolongation of the time spent in the urethra during surgery may impair urethral blood flow and cause ureteral epithelial disorders [7][8][9]. The aim of this study was to evaluate patients who underwent TURP and to investigate the demographic and clinical factors affecting the development of urethral stricture.…”

Aim This study aimed to investigate the incidence of urethral stricture during the early period after transurethral resection of the prostate (TURP) and the risk factors affecting the development of urethral stricture in patients treated in our clinic. Material and methods This retrospective study included patients who underwent TURP due to benign prostate hyperplasia (BPH) and had complete postoperative follow-up data of at least 12 months. Univariate and multivariate logistic regression analyses were performed to evaluate the relationship between urethral stricture and eight parameters (age, body mass index [BMI], prostate volume, number of comorbidities, amount of tissue removed, operative time, perioperative blood loss, and catheterization duration). Results Of the 3069 patients who underwent TURP in our clinic during the study period, 1740 patients with complete clinical data were included in the study. Mean age was 67.83 ± 5.80 years and mean body mass index (BMI) was 27.63 ± 4.31 kg/m 2 . Median preoperative prostate volume was 50.0 (range, 41.0-62.0) mm 3 and the average amount of tissue removed during surgery was 20.0 (range, 12.0-30.0) g. Urethral stricture was detected in 3.9% (67/1740) of the patients during a minimum of 12 months of follow-up period after TURP. In multivariate analysis, prolonged operative time and high comorbidity burden were found to be risk factors for urethral stricture ( p <0.001 for both). Conclusion Early urethral stricture remains an important complication of TURP. Our results show that prolonged operative time and high comorbidity burden are factors that increase the risk of urethral stricture.

“…Several radiation oncology studies have reported an increased risk of urethral stricture in patients who have undergone transurethral prostatectomy (TURP) prior to RT [16]. Studies have hypothesized that TURP prior to RT causes local damage, characterized by relative devascularization and reduced mucosal repair capacity [17].…”

Lower Urinary Tract Symptoms in Prostate Cancer Patients Treated With Radiation Therapy: Past and Present

et al. 2021

View full text Add to dashboard Cite

The incidence of prostate cancer (PCa) is increasing with the increase in aging population. Accordingly, interest and frequency of radiation therapy (RT) are also increasing. The types of RT may be broadly divided into external beam radiation therapy (EBRT), brachytherapy (BT), and combination therapy (EBRT + BT). The prevalence of lower urinary tract symptoms (LUTS) after RT for the treatment of PCa is common; however, there are few reviews on the relationship between RT and LUTS. Here, we review the causes and incidence of LUTS, as well as the evaluation and treatment options. Because of the reported risks of RT, patients undergoing RT should be counseled regarding the treatment challenges and informed that they may have higher failure rates than nonirradiated patients. Moreover, thorough evaluation and treatment strategies are needed to support treatment recommendations. With review of existing literature, this narrative article provides an overview to aid the urologist in treating patients presenting with complications associated with RT for the treatment of PCa. Further research is required to provide evidence of the effectiveness and feasibility of the management approach to the care of patients with LUTS after RT for the treatment of PCa.

“…5 Many risk factors have been associated with BNC, such as untreated preoperative urinary tract infection, small prostate volume, unsuitable resectoscope diameter, long operative time, history of prostatitis and postoperative Foley insertion. [5][6][7] The aim of the current study was to investigate the preoperative parameters associated with the occurrence of BNC after TURP or ThuP, and the difference in BNC incidence rates between TURP and ThuP.…”

Backgrounds: The aim of the present study was to investigate the preoperative parameters associated with bladder neck contracture (BNC) after transurethral resection of the prostate (TURP) or Thulium vaporesection, vapoenucleation or enucleation of the prostate (ThuP) and to compare the incidence of BNC after TURP and ThuP. Methods: Between March 2008 and March 2020, 2,363 patients received TURP and 1,656 patients received ThuP at Mackay Memorial Hospital. A total of 62 patients developed BNC. These BNC patients were age-and operation-matched to 124 randomly sampled TURP/ThuP controls without BNC. Results: Multivariate analysis showed that when compared with patients without BNC, those with BNC had smaller prostates (43.0±18.95 ml vs 57.2±19.84 ml, p<0.001), lower resection weight (11.64±11.75 g vs 16.67±12.84 g, p=0.001), shorter operative times (43.0±30.9 min vs 57.2±34.5, p<0.001), and slower resection speed (0.124±0.081 g/min vs 0.151±0.952 g/min, p=0.041). A greater proportion of BNC patients had history of cerebrovascular accidents (11/62 vs 7/124, p=0.009), coronary artery disease(14/48 vs 16/108, p=0.03), chronic kidney disease (14/62 vs 11/124, p=0.01), and two or more comorbidities (29/62 vs 27/124, p=0.001). A ROC curve predicted that a prostate volume <42.9cm3 was associated with a notably higher rate of BNC. Conclusion: This study demonstrated that incidence of BNC was the same in TURP and ThuP and low prostate volume, low resection speed and ≥2 comorbidities were positively correlated with the development of BNC after TURP or ThuP.
