Is emergency ureteroscopy justified in presence of infection or sepsis.

J Endourol 2020 Jun 2. Epub 2020 Jun 2.

Lokmanya Tilak Municipal Medical College and General Hospital, 29649, Mumbai, Mumbai, India, 400022;

We read with interest the article by Bakr and Abdelhalim, who conducted this rather bold study of evaluating the safety and efficacy of emergency ureteroscopy in patients presenting with mild sepsis [1]. Although the authors report good results in this clinical setting, we do have some reservations to the basic concept of this study and feel that ureteroscopy should not be performed in setting of known urinary infection, and surely not in presence of sepsis.

The Impact of Ureteral Access Sheath Use on the Development of Abnormal Postoperative Upper Tract Imaging after Ureteroscopy.

J Urol 2020 May 27:101097JU0000000000001147. Epub 2020 May 27.

Department of Urology, The Ohio State University Medical Center, Columbus, Ohio.

Introduction: Ureteral access sheaths (UAS) are commonly utilized during ureteroscopy (URS) to facilitate stone removal, improve visibility and maintain low intrarenal pressures. However, the use of a UAS can cause ureteral wall ischemia and ureteral tears, potentially increasing the risk of postoperative ureteral stricture and obstruction. The primary objective of this study was to study the impact that UAS use has on postoperative imaging studies. Read More

Efficacy and safety of various surgical treatments for proximal ureteral stone ≥10mm: A systematic review and network meta-analysis.

Int Braz J Urol 2020 May 18;46. Epub 2020 May 18.

Department of Urology, The Second Hospital of Hebei Medical University, Shijiazhuang, China.

We experienced a rare case of ureteropelvic junction disruption (UPJD) as a seat belt injury. A 19-year-old female was transferred after a car accident while wearing a seat belt. Computed tomography showed multiple fractures including Chance fracture dislocation of the first lumbar spine and right renal laceration with partial infarction. Read More

Aristolochic acid mutational signature defines the low-risk subtype in upper tract urothelial carcinoma.

Theranostics 2020 4;10(10):4323-4333. Epub 2020 Mar 4.

Key Laboratory of Genomics and Precision Medicine, Beijing Institute of Genomics, Chinese Academy of Sciences, Beijing 100101, China.

: Dietary exposure to aristolochic acids and similar compounds (collectively, AA) is a significant risk factor for nephropathy and subsequent upper tract urothelial carcinoma (UTUC). East Asian populations, who have a high prevalence of UTUC, have an unusual genome-wide AA-induced mutational pattern (COSMIC signature 22). Integrating mutational signature analysis with clinicopathological information may demonstrate great potential for risk ranking this UTUC subtype. Read More

J Endourol 2020 Apr 15. Epub 2020 Apr 15.

Johns Hopkins University School of Medicine, Baltimore, Maryland, United States;

Introduction: Accurate estimation of stone fragment size during ureteroscopic lithotripsy procedures facilitates operative efficiency and predicts the safety of fragment extraction or spontaneous passage. Using a novel stone measurement software application, this study assesses the feasibility of performing integrated, real-time digital stone measurement during ureteroscopy.

Methods: This workflow feasibility study was conducted in two phases. Read More

Risk Factors of Infectious Complications after Ureteroscopy: A Systematic Review and Meta-Analysis Based on Adjusted Effect Estimate.

Surg Infect (Larchmt) 2020 Apr 15. Epub 2020 Apr 15.

Department of Urology, Institute of Urology, Laboratory of Reconstructive Urology, West China Hospital, Sichuan University, Chengdu, Sichuan, P.R.China.

Multiple studies have reported that gender, pre-operative stent insertion, positive pre-operative urine culture results, and diabetes mellitus are associated with infectious complication after ureteroscopy. A previous meta-analysis focused on this topic is based, however, on crude estimate. Further analysis based on adjusted estimates is needed. Read More

Robot-assisted ipsilateral ureteroureterostomy in a duplex system utilizing intraoperative flexible ureteroscopy.

Urol Case Rep 2020 Jul 2;31:101158. Epub 2020 Apr 2.

Department of Surgery, University of Melbourne, Austin Hospital, Heidelberg, Australia.

Iatrogenic injury to the ureter during pelvic surgery is an uncommon but well-documented complication. Accurate identification of the ureter during pelvic surgery is made far more complex in the presence of a duplex or ectopic system, an anomaly occurring in up to 2% of the population. In this article we present a technique for robot-assisted ipsilateral ureteroureterostomy for treatment of iatrogenic injury of a lower pole moiety ureter in a complete duplex system. Read More

Robot-Assisted Simple Prostatectomy: Illustration of a Simplified Extraperitoneal Transcapsular Technique.

Videourology (New Rochelle) 2019 8;33(6). Epub 2019 Apr 8.

Department of Urology, University of Rochester Medical Center (URMC), Rochester, New York.

Robot-assisted simple prostatectomy (RASP) performed with the extraperitoneal (EP) technique (RASP-EP) minimizes the risk of bowel injury, particularly when bowel adhesions may be expected to be prominent, by negating the need to be in the transperitoneal space. However, there is a perception of its technical difficulty owing to the limited space that can be expanded within the space of Retzius. We aimed to describe, in the accompanying video, the step-by-step approach for a technically proficient procedure. Read More

Identifying a Break in the Chain: An Analysis of Where Ureteroscope Damage Occurs in the Hospital Cycle.

Urology 2020 Apr 9. Epub 2020 Apr 9.

Department of Urology, University of Kentucky, Lexington, KY.

Objective: To assess the timing and variables associated with damage to flexible ureteroscopes (fURS) at our institution. Flexible ureteroscopy is an important modality in the treatment of benign and malignant conditions of the upper urinary tract. While the durability and versatility of fURS have improved considerably, repair costs remain high and time out of commission diminishes workflow. Read More

What is the exact definition of stone dust? An in vitro evaluation.

Service d'Urologie, AP-HP, Hôpital Tenon, Assistance-Publique Hôpitaux de Paris, Sorbonne Université, 4 rue de la Chine, 75020, Paris, France.

Purpose: To propose a size-related definition of stone dust produced by lithotripsy of urinary stones.

Methods: Stone dust was defined as particles small enough to adhere to the following criteria: (1) spontaneous floating under 40 cm HO irrigation pressure; (2) mean sedimentation time of > 2 s through 10 cm saline solution; (3) fully suitable for aspiration through a 3.6 F working channel.

Contemporary role of multi-tract percutaneous nephrolithotomy in the treatment of complex renal calculi.

Asian J Urol 2020 Apr 28;7(2):102-109. Epub 2019 Dec 28.

Department of Urology, Muljhibhai Patel Urological Hospital, Nadiad, Gujarat, India.

Complex renal calculi remain to be a challenge for the treating urologist due to sheer bulk and the technicalities involved. Percutaneous nephrolithotomy (PCNL) remains the treatment modality of choice in dealing with these large and complex stones. The limiting factor in their treatment continues to be the need for using additional tracts or the use of flexible nephroscopy for complete stone clearance. Read More
