Summary: This study describes a new transurethral technique for distal ureter management and the improvement of intraoperative exposure during LESS-NU. The technique involves placing four channels through a transumbilical incision and using a laser working channel to cut the ureteral orifice. The results show that this technique is safe and efficient.

Summary: This study retrospectively evaluated 86 patients diagnosed with upper urinary tract urothelial carcinoma (UTUC) and found that single-position complete retroperitoneoscopic radical nephroureterectomy (SCRNU) is an efficient technique for UTUC treatment. The SCRNU group had shorter operating time, fewer perioperative complications, less postoperative pain, lower recurrence rate, and cheaper medical expenditure compared to the traditional retroperitoneoscopic nephroureterectomy (TRNU) group.

Summary: This study aimed to compare robot-assisted transperitoneal nephroureterectomy (TRNU) with robot-assisted retroperitoneal nephroureterectomy with bladder cuff (RRNU). The results showed no significant difference in intra- and postoperative complications between the two surgical techniques, but RRNU had significantly shorter surgery time and length of stay. RRNU is a safe and feasible treatment option, especially for patients with major previous abdominal surgery.

Summary: Robotic radical nephroureterectomy (RNU) has been increasingly used for patients with upper tract urothelial carcinoma in Korea, replacing open and laparoscopic RNU. The perioperative outcomes, 90-day complications, and oncological outcomes of robotic RNU were comparable to open and laparoscopic RNU. There were no significant differences in overall survival, progression-free survival, and cancer-specific survival between the surgical approaches.

Summary: In patients undergoing radical nephroureterectomy for upper tract urothelial carcinoma, managing the bladder cuff using the transvesical resection (TR) method was associated with better intravesical recurrence-free survival (IVRFS) and overall survival (OS) compared to the extravesical ligation (EL) method. However, EL was independently associated with intravesical recurrence, cancer-specific survival, and overall survival.

Summary: This study compared the outcomes of robot-assisted radical nephroureterectomy (RANU) and laparoscopic nephroureterectomy (LNU) for the treatment of upper urinary tract urothelial carcinoma (UTUC). The results showed that RANU and LNU had similar perioperative and oncologic outcomes, but RANU had lower intraoperative blood loss and shorter postoperative length of hospital stay.

Summary: A study analyzing data from 1,095 UTUC patients who underwent RNUx found that factors like history of bladder cancer, multifocal tumors, and preoperative ureteroscopy use were associated with intravesical recurrence. Active assessment for intravesical recurrence is recommended for at least 36 months post-RNUx.

Summary: The study found that patients who underwent radical nephroureterectomy for upper urinary tract urothelial cancer after radical cystectomy experienced poor overall survival and cancer-specific survival, with most surgeries being performed for locally advanced tumors. Independent risk factors for worse survival included UTUC T stage, presence of metastasis, and male gender.

Summary: This study retrospectively analyzed the techniques and outcomes of complete transperitoneal laparoscopic nephroureterectomy (CTLNU) and laparoscopic nephroureterectomy with open bladder cuff excision (LNOBE) for upper urinary tract urothelial carcinoma (UTUC). The results showed that CTLNU in a single position had advantages of shorter operation time, less blood loss, and shorter incision length.

Summary: For patients with multifocal UTUC, tumor distribution does not impact cancer-specific outcomes, but synchronous lesions are associated with a higher rate of bladder recurrence.

Summary: Comparing the effects of different combinations of radical nephroureterectomy (RNU) and bladder cuff excision (BCE) surgical procedures on intravesical recurrence (IVR) in patients with upper tract urothelial carcinoma (UTUC), it was found that minimally invasive RNU with open BCE is associated with a higher risk of IVR compared to open RNU with open BCE and MIS RNU with intracorporeal BCE.

Summary: This study aimed to investigate the prevalence and efficacy of endoscopic excision in patients with non-muscle invasive upper urothelial carcinoma (NMIUTUC) and compare them to radical nephroureterectomy (RNU). The results showed that endoscopic excision and RNU were equivalent in terms of oncologic outcomes for low-grade NMIUTUC, while endoscopic excision was associated with inferior prognosis for renal pelvis tumor and high-grade ureteral tumor.

Summary: This study investigated the natural course of polypoid lesions in the ureter during ureteroscopic stone surgery. It was found that fibroepithelial polyps do not disappear in follow-up ureteroscopy, but the rate of postoperative hydronephrosis is not higher compared to inflammatory polyps. The number of resected polyps is closely related to the occurrence of postoperative ureteral stricture and moderate-to-severe hydronephrosis.

Summary: Microbiota plays a role in kidney stone formation through various mechanisms, including hyperoxaluria, calcium oxalate supersaturation, biofilm formation, and urothelial injury. The urinary tract microbiome differs between cohorts with and without urinary stone disease, and certain bacteria are associated with stone formation. Standardization is essential in urinary microbiome research for urolithiasis.

Summary: This study investigated the prediction of urinary stone composition using a convolutional neural network (CNN) on single-use flexible ureterorenoscopic (fURS) images with low resolution. The CNN model achieved decent results with an accuracy of 81.8% in distinguishing between stones containing calcium oxalate and those without. The study demonstrates the potential of CNN in predicting stone composition even in challenging conditions.

Summary: This study systematically evaluated the role of cytoreductive prostatectomy (CRP) in the oncologic outcomes of oligometastatic prostate cancer (OmPCa). The results showed that patients who underwent CRP had better oncologic outcomes compared to the control group, particularly in terms of time to castration-resistant prostate cancer (CRPCa) and overall survival (OS).
