RESUMO
PURPOSE: To investigate the safety of transurethral ureteroscopy (URS) for urolithiasis in bedridden patients and to identify bedridden patient-specific risk factors for postoperative complications. METHODS: The patients who underwent URS for urolithiasis were divided into bedridden patients and good performance status (PS) patients, and the groups were compared regarding their clinical characteristics and postoperative complications. A multivariable logistic regression analysis was performed to evaluate independent predictors of postoperative febrile urinary tract infection (fUTI). RESULTS: A total of 1626 patients were included, 276 in the bedridden patient group, and 1350 in the good PS patient group. The bedridden patient group had a significantly higher age and higher proportion of females and had multiple comorbidities. In 77 patients (27.9%), 88 postoperative complications developed for the bedridden patient group. Clavien-Dindo grade III or IV complications were observed in only 8 patients. No grade V complications were observed. The most common complication was fUTI. The frequency of fUTI with grade III or IV for the bedridden patient group (2.2%) was higher compared with the good PS patient group (0.5%), but the difference was not statistically significant (p = 0.13). Bedridden patient-specific risk factors for fUTI included female sex, diabetes mellitus, cerebrovascular comorbidities, lower extremity contracture, and prolonged operative time. CONCLUSION: URS for urolithiasis is a feasible and acceptable procedure in bedridden patients, despite the moderate rate of postoperative complications. The identified risk factors provide a framework for risk stratification and individualized care in this unique patient population.

BACKGROUND: This study aimed to investigate factors, including the degree of hydronephrosis, that may be associated with decreased renal function after radical nephroureterectomy (RNU). METHODS: This study included 252 patients who underwent laparoscopic RNU with an estimated glomerular filtration rate (eGFR) ≥ 30 ml/min/1.73 m2 in three institutions. We assessed the association between hydronephrosis grade and perioperative renal function and performed a stepwise multivariate linear regression analysis to identify factors associated with postoperative eGFR. Patients with preoperative eGFR ≥ 50 ml/min/1.73 m2 were divided into a training set and an independent external validation set to develop a predictive model for postoperative renal function. RESULTS: The median preoperative and postoperative eGFR were 61.1 and 46.4 ml/min/1.73 m2, respectively. The eGFR preservation rates were 66.9%, 66.6%, 88.1%, and 100.0% in groups without, with mild, moderate, and severe hydronephrosis, respectively, and this difference was statistically significant (p < 0.001). Multivariate analysis revealed that factors predictive of postoperative eGFR included sex, preoperative eGFR, clinical T stage (cT3-4), and the presence of moderate or severe hydronephrosis. Our predictive model, based on these factors, positively correlated with actual postoperative renal function, and the similarity in categories with or without renal function insufficiency between predicted and actual postoperative renal functions was 78% in both training and validation sets. CONCLUSION: Moderate or severe hydronephrosis is associated with a modest postoperative decline in renal function, while mild hydronephrosis is not. Our predictive model may be useful in predicting postoperative renal function insufficiency and guiding decision-making for perioperative medical treatment.

In cases of rectal invasion by locally invasive prostate cancer (LAPC) leading to severe pain or bleeding, total pelvic exenteration (TPE) is necessary. Here, we present two cases of successful minimally invasive TPE: one performed laparoscopically for local recurrence with rectal bleeding after laparoscopic radical prostatectomy, and another done robotically for LAPC (clinical T4N1M0) accompanied by rectal bleeding. Medical treatments were ineffective in the latter case, and the tumor occupied a significant portion of the pelvis. We adopted a simultaneous transperineal approach and performed intracorporeal ileal conduit formation. Our cases highlight the challenging nature of minimally invasive TPE for symptomatic LAPC. Despite its complexity, these techniques prove viable and valuable in managing LAPC-related symptoms, emphasizing their practical utility in clinical settings.
