Abstract
BACKGROUND It is controversial whether the use of a double-J stent (DJ) in patients with bladder cancer before radical cystectomy (RC) increases the risk of tumour seeding in the upper tract and thus the risk of metachronous upper tract urothelial carcinoma (UTUC). The aim of our study is to investigate the risk of upper tract recurrence after RC in patients previously managed with a DJ stent. METHODS A total of 699 patients who had undergone RC between January 2003 and March 2022 with complete perioperative data and pathological outcome were included in our study. Patients treated preoperatively with a DJ stent were identified and compared for development of metachronous UTUC with those who did not receive prior internal stenting. Multivariable Cox regression analysis was used to determine predictors of UTUC occurrence among the possible pathological features; risk factors for mortality after RC were also examined. RESULTS Of 699 patients, 117 (16.7%) were managed preoperatively with a DJ stent. The overall probability of metachronous UTUC was 1%, 4% and 6% at 1, 3 and 5 years, respectively. The groups with and without DJ stenting were comparable regarding their clinicopathologic features, except for the higher incidence of hydronephrosis in the DJ group. At similar follow-up periods (median follow-up 32 months), metachronous UTUC was detected in four (3.4%) patients in the DJ group and in 13 (2.2%) in the non-stented group (P=0.44). The median interval (IQR) from cystectomy to UTUC was 40.5 (20-49) months in the DJ group and 37 (24-82) in the non-stented group (P=0.7). In the multivariable analysis, only presence of CIS (HR 3.83, 95% CI 1.19-12.29, P=0.024) and positive ureteral margin (HR=5.2, 95% CI 1.38-19.57, P=0.015) were predictors of metachronous UTUC. The study is limited by the retrospective nature and relatively short follow-up. CONCLUSIONS Ureteral stenting for management of hydronephrosis in patients with bladder cancer undergoing RC is a viable option, without higher risk for UTUC or mortality. Patients with positive ureteral margin and CIS are considered high-risk groups for upper tract recurrence and should receive long-term, rigorous follow-up.

Obstructive uropathy: Overview of the pathogenesis, etiology and management of a prevalent cause of acute kidney injury. World J Nephrol 2024; 13:93322. [PMID: 38983763 PMCID: PMC11229834 DOI: 10.5527/wjn.v13.i2.93322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 05/24/2024] [Accepted: 06/18/2024] [Indexed: 06/25/2024] Open
Abstract
Obstructive uropathy is defined as the structural or functional interruption of urinary outflow at any level in the urinary tract. It is regarded as one of the most prevalent causes of acute kidney injury (AKI), accounting for 5%-10% of cases. Acute severe obstruction of the urinary tract is a potentially threatening situation for the kidneys and therefore requires prompt identification and management to relieve obstruction. The aim of the present article is to review and synthesize available evidence on obstructive uropathy, providing a clinical guideline for clinicians. A literature review on obstructive uropathy in the context of AKI was performed, focusing on the least clarified aspects regarding diagnosis and management. Recent literature searching was conducted in English and top-level evidence articles including systematic reviews, metanalyses and large series were prioritized. Acute obstruction of the urinary tract is a diagnostic and therapeutical challenge that may lead to important clinical complications together with direct structural and hemodynamic damage to the kidney. Early recognition of the leading cause and its exact location is essential to ensure prompt urinary drainage together with the most suitable drainage technique selection. A multidisciplinary approach, including urologists, nephrologists, and other medical specialties, is best suited to correctly manage concomitant hemodynamic changes, fluid and electrolyte imbalances, and other related issues. Obstructive uropathy is one of the leading causes of AKI. Recognition of patients suitable for early diversion and feasibility or adequate selection of the indicated technique is sometimes challenging. A thorough understanding of the physiopathology behind the development of urinary obstruction is vital for correct diagnosis and management.

Assessing the Impact of Percutaneous Nephrostomy Presence on Neoadjuvant Treatment Quality in Patients With Muscle Invasive Bladder Cancer. Clin Genitourin Cancer 2024; 22:491-496. [PMID: 38267303 DOI: 10.1016/j.clgc.2024.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 01/02/2024] [Accepted: 01/02/2024] [Indexed: 01/26/2024]
Abstract
INTRODUCTION Symptomatic hydronephrosis associated with muscle invasive bladder cancer (MIBC) necessitates percutaneous nephrostomy (PCN) insertion before neoadjuvant chemotherapy (NAC). This study assesses the impact of PCN presence on standard intended NAC quality, its related complications and outcome after radical cystectomy (RC). MATERIALS AND METHODS The study comprises a retrospective, multicenter cohort of 193 consecutive RCs performed between 2016 and 2019. Eighty (42%) of these patients received NAC and were divided in 2 comparison groups by presence (n = 26; 33%) or absence (n = 54; 67%) of PCN. Endpoints included completion of adequate NAC treatment (cisplatin-based chemotherapy for at least 4 courses), complications during NAC, post-RC complications and hospital stay. RESULTS Overall, patients with PCN (45/193; 23%) featured a higher referral rate to NAC (58% vs. 36%, P = .01), worse glomerular filtration rates (P < .001) and more adverse events (P = .04), in comparison to non-PCN patients. In the NAC cohort, PCN patients had less adequate treatment rates (54% vs. 85%, P = .005), and more infections (35% vs, 7%; P = .008) and hospitalizations (58% vs. 13%; P < .001) during chemotherapy. Post-RC outcome was similar for both comparison groups. PCN was an independent risk factor for inadequate NAC (OR = 3.9, P = .04), and infections (OR = 11.3, P = .01) and hospitalizations (OR = 7.5, P = .004) during NAC. CONCLUSIONS PCN in MIBC patients is a significant risk factor for inadequate NAC and adverse events during treatment. This finding may quire the rationale of NAC, potentially leading to consideration of NAC avoidance and upfront RC in PCN patients. Further survival studies with long follow-up are needed for elucidating this issue.

Abstract
Transurethral resection of bladder tumors (TURBT) is the standard of care for the diagnostics and primary treatment of bladder tumors. These are removed by fragmentation using loop diathermy. The resection area is coagulated for hemostasis. An important aspect is always a complete resection with an adequate amount of detrusor muscle in the specimen. Postoperative intravesical instillation of single-shot chemotherapy has been proven to reduce recurrence rates. Methods for improved tumor visualization (particularly photodynamic diagnostics) are used to enhance tumor detection rates particularly in multifocal tumors or carcinoma in situ (CIS). Thus, recurrence and progression rates can be reduced. Depending on the histological examination of the TURBT specimen, follow-up treatment for non-muscle invasive bladder tumors are adjuvant instillation treatment using chemotherapy or Bacillus Calmette-Guérin (BCG), second look TURBT and early cystectomy or for muscle invasive bladder tumors, radical cystectomy or (oncologically subordinate) trimodal treatment with renewed TURBT, radiotherapy and chemotherapy are indicated. Possible complications of TURBT include bleeding with bladder tamponade, extraperitoneal or intraperitoneal bladder perforation and infections of the urogenital tract.

Intraoperative upper urinary tract cytology examination is a risk factor of upper urinary tract recurrence in patients with non-muscle-invasive bladder cancer. Urol Oncol 2020; 39:75.e9-75.e16. [PMID: 32665123 DOI: 10.1016/j.urolonc.2020.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 05/16/2020] [Accepted: 06/13/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To evaluate the impact of intraoperative upper urinary tract (UUT) cytology examination in patients with non-muscle-invasive bladder cancer (NMIBC) who had undergone transurethral resection of bladder tumor (TURBT). MATERIALS AND METHODS We retrospectively evaluated 414 patients with NMIBC who had undergone transurethral resection of bladder tumor between November 1993 and April 2019. Patients with simultaneous UUT urothelial carcinoma (UC) detected via computed tomography were excluded. Patients were divided into 2 groups: those who had undergone intraoperative bilateral UUT cytology examination via retrograde catheterization (study group) and those who had not (control group). We evaluated the utility of intraoperative UUT cytology examination, comparing surgical outcomes and perioperative complications between the 2 groups. In addition, we evaluated the impact of UUT cytology examination on UUT recurrence using background-adjusted multivariate analysis. RESULTS We obtained 292 UUT urine samples from 146 patients with a median age of 72 years. Of 292 UUT urine samples, 11 (3.7%) were positive and 3 were finally diagnosed as UUT UC. Positive predictive value and false positive rate were 18% and 3.1%, respectively. Operative time for the study group was significantly longer than for the control group. Rate of perioperative complications were not significantly different between the 2 groups. However, in background-adjusted multivariate analysis, intraoperative UUT cytology examination was associated with significantly shorter UUT recurrence-free survival. CONCLUSION Intraoperative UUT cytology examination may not be recommended as a result of low positive predictive value due to contamination and UUT recurrence risk in patients with NMIBC.
