Oncologic and Safety Outcomes for Retrograde and Antegrade Endoscopic Surgeries for Upper Tract Urothelial Carcinoma: A Systematic Review and Meta-analysis. Eur Urol Focus 2022; 9:258-263. [PMID: 36428210 DOI: 10.1016/j.euf.2022.11.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 11/02/2022] [Accepted: 11/11/2022] [Indexed: 11/24/2022]
Abstract
The aim of this study was to identify and summarize available data on oncologic and safety outcomes for retrograde versus antegrade endoscopic surgery in patients with upper tract urothelial carcinoma (UTUC). We systematically searched studies reporting on endoscopic surgery in patients with UTUC. The primary outcome of interest was oncologic control, including bladder and upper urinary tract recurrences. The secondary outcomes were any-grade and major complications. Twenty studies comprising 1091 patients were included in our analysis. The pooled bladder recurrence rate was 35% (95% confidence interval [CI] 28.0-42.3%; I2 = 48%) after retrograde endoscopic surgery and 17.7% (95% CI 6.5-32.1%; I2 = 29%) after antegrade endoscopic surgery. The pooled upper urinary tract recurrence rate was 56.4% (95% CI 41.2-70.9; I2 = 93%) after retrograde endoscopic surgery and 36.2% (95% CI 25.5-47.6%; I2 = 57%) after antegrade endoscopic surgery. The pooled complication rate was 12.5% (95% CI 0.8-32.8%; I2 = 94%) for any-grade complications and 6.6% (95% CI 0.1-19.1%; I2 = 89%) for major complications in the retrograde endoscopic cohort. In summary, our analyses suggest promising oncologic benefits of antegrade kidney-sparing surgery in terms of bladder and upper urinary tract recurrence rates in UTUC. Retrograde endoscopic surgery is a safe procedure with a minimal risk of complications and acceptable oncologic outcomes. Research should address the hypothesis that endoscopic antegrade surgery can be a safe and effective alternative for well-selected patients. PATIENT SUMMARY: One of the surgical options for treatment of cancer of the upper urinary tract is removal of the tumor through a small telescope called an endoscope. The endoscope can be inserted via the urethra (called a retrograde approach) or through a small incision in the skin (antegrade approach). Our review shows that the antegrade approach seems to provide acceptable cancer control rates. Further research could help to identify the role for endoscope surgery in cancer of the upper urinary tract.

Abstract
Iatrogenic injury is unfortunately a leading cause of morbidity and mortality for patients worldwide. The etiology of iatrogenic injury is broad, and can be seen with both diagnostic and therapeutic interventions. While steps can be taken to reduce the occurrence of iatrogenic injury, it is often not completely avoidable. Once iatrogenic injury has occurred, prompt recognition and appropriate management can help reduce further harm. The objective of this narrative review it to help reader better understand the risk factors associated with, and treatment options for a broad range of potential iatrogenic injuries by presenting a series of iatrogenic injury cases. This review also discusses rates, risk factors, as well as imaging and clinical signs of iatrogenic injury with an emphasis on endovascular and minimally invasive treatments. While iatrogenic vascular injury once required surgical intervention, now minimally invasive endovascular treatment is a potential option for certain patients. Further research is needed to help identify patients that are at the highest risk for iatrogenic injury, allowing patients and providers to reconsider or avoid interventions where the risk of iatrogenic injury may outweigh the benefit. Further research is also needed to better define outcomes for patients with iatrogenic vascular injury treated with minimally invasive endovascular techniques verses conservative management or surgical intervention.

Abstract
With the recent technological advancements in endourology, retrograde intrarenal surgery has become a more popular procedure for treatment of urolithiasis. Furthermore, since the introduction of new laser systems and advanced flexible ureteroscopy with miniaturized ureteroscopes, the treatment indications for retrograde intrarenal surgery have expanded to include not only larger renal stones of >2 cm but also upper urinary tract urothelial carcinoma, ureteral stricture, and idiopathic renal hematuria. Clinicians must keep up with these trends and make good use of these technologies in the rapidly changing field of endourology. Simultaneously, we must consider the risk of various complications including thermal injury due to laser use, ureteral injury caused by the ureteral access sheath, and radiation exposure during retrograde intrarenal surgery with fluoroscopic guidance. This review focuses on the past, present, and future of retrograde intrarenal surgery and provides many topics and clinical options for urologists to consider.

Abstract
OBJECTIVES To compile and examine safety data from clinical studies of endoscopic management of patients with low-grade upper tract urothelial carcinoma (UTUC) to identify rates and factors associated with reported complications. METHODS Ovid Medline and Ovid Medline Daily (with Embase as secondary search) including citations from 1946-2018 were queried using the following terms: ureteroscopy, ureter, catheter, endoscopy, complication, adverse events, morbidity, ablation, laser, upper tract urothelial carcinoma, ureteral stricture, ureteral stenosis, and ureteral injury. Abstracts were reviewed for relevance; diagnostic studies, case studies, and reviews were excluded. RESULTS Thirty-eight publications (7 prospective, 31 retrospective) representing >1100 patients were identified. Ureteral stricture was the most frequently reported complication (studies; rates) (26/38; 0-27%), with incidence associated with number of procedures and treatment method. Bleeding, infection, and fever were most common with adjuvant treatment (BCG or mitomycin). Serious and fatal complications were rare. CONCLUSIONS Ureteral stricture is the most frequent complication of endoscopic UTUC management but can be managed successfully in most cases. Most complications were minor. Although additional prospective studies are needed, these results support the safety of ureteroscopic management of UTUC in appropriately selected patients.

Abstract
INTRODUCTION The conservative management of upper tract urothelial carcinoma (UTUC) has historically been offered to patients with imperative indications. The recent International Consultation on Urologic Diseases (ICUD) publication on UTUC stratified treatment allocations based on high- and low-risk groups. This report updates the conservative management of the low-risk group. METHODS The ICUD for low-risk UTUC working group performed a thorough review of the literature with an assessment of the level of evidence and grade of recommendation for a variety of published studies in this disease space. We update these publications and provide a summary of that original report. RESULTS There are no prospective randomized controlled studies to support surgical management guidelines. A risk-stratified approach based on clinical, endoscopic, and biopsy assessment allows selection of patients who could benefit from kidney-preserving procedures with oncological outcomes potentially similar to radical nephroureterectomy with bladder cuff excision, with the added benefit of renal function preservation. These treatments are aided by the development of high-definition flexible digital URS, multi-biopsies with the aid of access sheaths and other tools, and promising developments in the use of adjuvant topical therapy. CONCLUSIONS Recent developments in imaging, minimally invasive techniques, multimodality approaches, and adjuvant topical regimens and bladder cancer prevention raise the hope for improved risk stratification and may greatly improve the endoscopic treatment for low-risk UTUC.
