Background: Although previous literature shows tumor location as a prognostic factor in upper tract urothelial carcinoma (UTUC), there remains uninvestigated regarding the impact of tumor location on grade concordance and discrepancies between ureteroscopic (URS) biopsy and final radical nephroureterectomy (RNU) pathology. Methods: In this international study, we retrospectively reviewed the records of 1,498 patients with UTUC who underwent diagnostic URS with concomitant biopsy followed by RNU between 2005 and 2020. Tumor location was divided into four sections: the calyceal-pelvic system, proximal ureter, middle ureter, and distal ureter. Patients with multifocal tumors were excluded from the study. We performed multiple comparison tests and logistic regression analyses. Results: Overall, 1,154 patients were included; 54.4% of those with low-grade URS biopsies were upgraded on RNU. In the multiple comparison tests, middle ureter tumors exhibited the highest probability of upgrading, meanwhile pelvicalyceal tumors exhibited the lowest probability of upgrading (73.7% vs 48.5%, p = 0.007). Downgrading was comparable across all tumor locations. On multivariate analyses, middle ureteral location was significantly associated with a low probability of grade concordance (odds ratio [OR] 0.59; 95% confidence interval [CI], 0.35-1.00; p = 0.049) and an increased risk of upgrading (OR 2.80; 95% CI, 1.20-6.52; p = 0.017). The discordance did not vary regardless of caliceal location, including the lower calyx. Conclusions: Middle ureteral tumors diagnosed to be low grade had a high probability to be undergraded. Our data can inform providers and their patients regarding the likelihood of undergrading according to tumor location, facilitating patient counseling and shared decision making regarding the choice of kidney sparing vs RNU.

CONTEXT: Radical nephroureterectomy (RNU) with bladder cuff resection is the standard treatment in patients with high-risk upper tract urothelial cancer (UTUC). However, it is unclear which specific surgical technique may lead to improve oncological outcomes in term of intravesical recurrence (IVR) in patients with UTUC. OBJECTIVE: To evaluate the efficacy of surgical techniques and approaches of RNU in reducing IVR in UTUC patients. EVIDENCE ACQUISITION: Three databases were queried in January 2024 for studies analyzing UTUC patients who underwent RNU. The primary outcome of interest was the rate of IVR among various types of surgical techniques and approaches of RNU. EVIDENCE SYNTHESIS: Thirty-one studies, comprising 1 randomized controlled trial and 1 prospective study, were included for a systematic review and meta-analysis. The rate of IVR was significantly lower in RNU patients who had an early ligation (EL) of the ureter compared to those who did not (HR: 0.64, 95% CI: 0.44-0.94, p = 0.02). Laparoscopic RNU significantly increased the IVR compared to open RNU (HR: 1.28, 95% CI: 1.06-1.54, p < 0.001). Intravesical bladder cuff removal significantly reduced the IVR compared to both extravesical and transurethral bladder cuff removal (HR: 0.65, 95% CI: 0.51-0.83, p = 0.02 and HR: 1.64, 95% CI: 1.15-2.34, p = 0.006, respectively). CONCLUSIONS: EL of the affected upper tract system, ureteral management, open RNU, and intravesical bladder cuff removal seem to yield the lowest IVR rate in patients with UTUC. Well-designed prospective studies are needed to conclusively elucidate the optimal surgical technique in the setting of single post-operative intravesical chemotherapy.

We systematically reviewed the literature and summarized oncologic and safety outcomes for endoscopic management (EM) compared to radical nephroureterectomy (RNU) for patients with upper tract urothelial carcinoma (UTUC). Studies comparing oncologic and/or safety results for EM versus RNU in patients with UTUC were included in our review. Overall, 13 studies met the criteria, and five studies were included in a meta-analysis using adjusted hazard ratios (HRs) for overall survival (OS), cancer-specific survival (CSS), and bladder recurrence-free survival (BRFS). EM was associated similar OS (HR 1.27, 95% confidence interval [CI] 0.75-2.16), CSS (HR 1.37, 95% CI 0.99-1.91), and BRFS (HR 0.98, 95% CI 0.61-1.55) to RNU, while 28-85% of patients treated with EM experienced upper tract recurrence across the studies. EM required more interventions with a higher cumulative risk of complications and lower likelihood of renal preservation. In summary, EM for low-grade UTUC had comparable survival outcomes to RNU at the cost of higher local recurrence rates resulting in a need for long-term rigorous surveillance and repeated interventions. PATIENT SUMMARY: For selected cases of cancer in the upper urinary tract, surgical treatment via a telescope inserted through the urethra or the skin (endoscope) results in cancer control outcomes that are comparable to those after removal of the kidney and ureter. However, because of its higher rate of local recurrence, this approach requires repeated endoscopic treatment sessions. Patients should be well informed about these issues to help in shared decision-making.

OBJECTIVE: To assess the incidence of ureteric injuries, clinical value of prophylactic ureteric stenting and impact of intra- or postoperative detection of ureteric injuries in patients treated with gynaecological or colorectal surgery. METHODS: Multiple databases were searched for articles published before September 2021 according to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement. Studies were deemed eligible if they evaluated the differences in the rate of ureteric injuries between laparoscopic and open surgery, prophylactic ureteric stenting or not, and those of final treatment success between intra- and postoperative detection in patients who underwent gynaecological or colorectal surgery. RESULTS: Overall, 46 studies were eligible for this meta-analysis. Compared to open surgery, laparoscopic hysterectomy was associated with a higher incidence of ureteric injuries (pooled odds ratio [OR] 2.12, 95% confidence interval [CI] 1.71-2.62), but there was no statistically significant difference in colectomy (pooled OR 0.89, 95% CI 0.77-1.03). Prophylactic ureteric stenting was associated with a lower incidence of ureteric injuries during gynaecological surgery (pooled OR 0.61, 95% CI 0.39-0.96). The number needed to perform ureteric stenting to prevent one ureteric injury was 224 in gynaecological surgery. On the other hand, prophylactic ureteric stenting did not reduce the risk of ureteric injuries during colorectal surgery. Intraoperative detection of a ureteric injury was associated with a lower rate of complication management failure compared to postoperative detection (pooled OR 0.22, 95% CI 0.12-0.41). CONCLUSIONS: Laparoscopic hysterectomy seems to be associated with a higher rate of ureteric injuries compared to an open approach. Prophylactic ureteric stenting seems to reduce this risk during gynaecological surgery. Intraoperative detection of a ureteric injury during abdominal/pelvic surgery improves outcomes, suggesting the need for awareness and proactive problem identification. Further well-designed studies assessing the candidates who are more likely to benefit from prophylactic ureteric stenting including cost analysis are needed.

Ileus je jedna z nejzávažnějších diagnóz ze skupiny náhlých příhod břišních. Nemalá část nemocných trpících některými formami střevní neprůchodnosti reaguje dobře na konzervativní léčbu. Avšak v některých situacích může dojít k prodlení rozpoznání ileu strangulačního s následnou vysokou morbiditou a mortalitou v těchto případech. Naše práce prezentuje kazuistiku 81leté pacientky, u které se rozvinula neprůchodnost střevní krátce po stentáži ureteru, provedené pro obstrukční hydroureteronefrózu. Příčinou strangulace kliček tenkého střeva bylo atypické uložení pravostranného ureteru v dutině břišní. Ileus má několik typů. Podle příčiny se dá rozdělit na mechanický, neurogenní a cévní.

Ileus is one of the most severe diagnoses of the group of acute abdomen events. Some patients with certain forms of bowel obstruction respond well to conservative therapy. However, the diagnosis of strangulation ileus can be delayed in some situations, resulting in high morbidity and mortality in such cases. Our paper presents the case of an 81-year-old female patient who developed an ileus shortly after ureteral stent placement due to obstructive hydroureteronephrosis. The strangulation of the small intestine was caused by an atypical position of the right ureter in the abdominal cavity.

OBJECTIVES: We evaluated the feasibility, safety, and long-term outcomes of pyelovesicostomy as an alternative surgical treatment for complex ureteral lesions after kidney transplant. MATERIALS AND METHODS: A single-center, retrospective, observational cohort study was conducted on 5 adult kidney transplant recipients who underwent pyelovesicostomy between January 2000 and June 2023. The collected data included patient demographics, surgery indication, time from transplant to pyelovesicostomy, procedure details, and kidney function at various time points after surgery. Primary outcomes were allograft function and complications. RESULTS: The 5 patients (4 female, 1 male) had a mean age of 65.8 years and mean body mass index of 26.8. Indications were complex ureteral lesions. The time between transplant and reoperation ranged from 4 days to 12 years. Renal function improved for all patients, with a progressive decrease in mean serum creatinine concentration. The mean follow-up period extended to 7 years. One patient died with the graft still functional at 20 years after the operation, whereas the remaining 4 patients continue to live with functional grafts. CONCLUSIONS: Our study suggests that pyelovesicostomy may provide a potent alternative for the management of complex ureteral lesions after kidney transplant. We have observed good short-term and long-term outcomes in specific patients, pointing toward a promising avenue oftreatment worth further exploration. This reaffirms the importance of a personalized approach in medicine, to consider each patient's unique conditions and characteristics during therapeutic decisions.

Dilatace kalichopánvičkového systému je nejčastěji zjišťovanou abnormitou při prenatálním a postnatálním ultrazvukovém screeningu ledvin a močových cest. Často je doprovázena také rozšířením močovodu (megaureter). Ve více než 60 % případů nález spontánně mizí s věkem v důsledku vyzrávání uropoetického systému. Pokud ne, podílí se na etiologii dilatace (mimo vezikoureterální reflux) zejména vrozené překážky v odtoku moči. Jejich obvyklou lokalizací je oblast pelviureterálního a vezikoureterálního přechodu, převážně se přitom jedná o faktory intraluminální. Z celkově méně často zastoupených extraluminálních příčin obstrukce se v praxi nejčastěji setkáváme s křížící aberantní cévou utlačující ureter v jeho subrenálním průběhu. V těchto případech odstupuje aberantní tepna z aorty a směřuje mimo oblast cévního hilu k dolnímu pólu ledviny, pro který je hlavním zdrojem cévního zásobení. V místě křížení ureteru pak může znesnadňovat jeho průchodnost (1). Prezentovaná kazuistika popisuje zcela výjimečnou příčinu symptomatické obstrukce močových cest cévní etiologie - atypické křížení a útlak ureteru ovarickými cévami.

Pelvicalyceal dilatation is the most common abnormity identified in ultrasound screening of the urinary tract. Often it is accompanied by dilatation of the ureter too (megaureter). In more than 60% of all cases this finding disappears with age due to maturation of the urinary tract. Otherwise, there are mainly congenital narrowings paticipating in the etiology of dilatation (except for vesicoureteral reflux). It ́s usual location is the pelviureteral and vesicoureteral junction and most of them are represented by intraluminal factors. As regards extraluminal causes of obstruction most often we can see aberant vessels crossing ureter in it ́s subrenal course. In these cases the aberant vessel is a branch of the aorta and points toward lower pole of the kidney as the main source of its blood suply. At the site of crossing the ureter there may be a difficult outflow of the urine. Our case represents an extraordinary cause of the symptomatic vascular obstruction of the urinary tract - atypical crossing and oppression of the ureter by ovaric vessels.
