Background: The aim of this study is to investigate the cumulative incidence and risk factors of postoperative inguinal hernia (PIH) in patients undergoing radical prostatectomy, i.e., laparoscopic prostatectomy (LRP) and robot-assisted laparoscopic prostatectomy (RARP).
Methods: This study included 1124 patients who had undergone radical prostatectomy or transurethral resection of bladder tumor from 2011-2016. We compared the cumulative incidence of PIH in the radical prostatectomy groups (460; LRP 341, RARP 119) and the control group (664; transurethral resection of bladder tumor), and we then analyzed the risk factors (age, operative methods, previous abdominal operative history, thickness and width of external oblique muscle and rectus muscle, thickness of abdominal subcutaneous fat layer at Hesselbach's triangle level, body mass index, prostate-specific antigen, operative time, specimen weight, Gleason score, and pathology T-stage) of PIH in the radical prostatectomy groups.
Results: The median follow-up period in this study was 39.6 months. In Kaplan-Meier curve analysis, the cumulative incidence of PIH was 5.3, 4.2, and 0.5% for the LRP, RARP, and control groups, respectively (p < 0.001). Multiple logistic regressions showed that thickness of external oblique muscle and width of rectus muscle were significant risk factors (p < 0.001 and p = 0.027).
Conclusions: PIH is considered to be one of the complications of LRP and RARP. Moreover, we suggest that if the thickness of the muscle is <7.3 mm, thoughtful surgical manipulation is needed for radical prostatectomy, and care should be taken to determine whether hernia occurs during follow-up.
Objective: Urinary continence after radical prostatectomy is a crucial aspect of patient quality of life. The aim of this study was to identify the factors influencing urinary continence after robot-assisted laparoscopic radical prostatectomy, focusing on the role of anterior reconstruction.
Methods: We collected clinical data from 375 patients at a single institution.
Objectives: This study aimed to evaluate predictors of late biochemical recurrence in patients with no recurrence at 5 years after radical prostatectomy (RP).
Methods: We retrospectively investigated patients who underwent RP for prostate cancer in our institute from 1999 to 2016, selecting those with no biochemical recurrence at 5 years post-RP. These patients did not receive neoadjuvant and adjuvant hormone therapy.
Background: This study aims to assess the relationship between body mass index (BMI) and prostate volume, utilizing pre and postoperative measurements.
Methods: A retrospective, observational study was conducted at a single site using data from an institutional database. Medical records of patients who underwent robot-assisted radical prostatectomy were reviewed.
Objective: To evaluate the efficacy of a machine learning model for predicting prostate-specific antigen (PSA) persistence after radical prostatectomy (RP).
Methods: Data from 470 patients who underwent RP at the Affiliated Hospital of Qingdao University from January 2018 to June 2021 were retrospectively analyzed. Ten risk factors, including age, body mass index (BMI), preoperative PSA, biopsy Gleason score, total prostate specific antigen density (PSAD), clinical tumor stage, clinical lymph node status, seminal vesicle invasion, capsular invasion and positive surgical margin, were included in the analysis.
