Posterior cloaca: A urogenital rather than anorectal anomaly.

J Pediatr Urol 2021 06 20;17(3):410.e1-410.e7. Epub 2021 Jan 20.

Pediatric Surgery Department, Faculty of Medicine, Ain Shams University, Egypt.

Background: 'Persistent Cloaca' refers to one of the major groups of anorectal anomalies in the female when a single perineal orifice is located at the normal site of the urethra draining both urogenital and alimentary tracts. However, 'posterior cloaca' is a new term developed by Pena to describe a unique defect in females in which a common urogenital sinus is deviated posteriorly to open into normally located anorectum (type A) or in the perineum slightly anterior to the anus (type B).

Methods: The study included seven girls diagnosed as posterior cloaca. Read More

Trans-urethral snare stent removal: a novel, self-constructed innovation for simultaneous ureteral stent removal and safety guidewire insertion.

ANZ J Surg 2021 Apr 2;91(4):571-577. Epub 2021 Feb 2.

Department of Urology, Royal Melbourne Hospital, Melbourne, Victoria, Australia.

Background: Ureteral stent insertion and subsequent removal remains one of the most common procedures performed in endourology. We aimed to evaluate a novel, one-step method, permitting simultaneous stent removal and guidewire passage using a self-constructed suture snare via standard cystoscopy. This method should be used prior to ureteroscopy, in cases of minimal stent encrustation and peri-ureteral mucosal oedema, where identification and subsequent cannulation of the ureteral orifice may be a challenge.

Results of a previously unreported extravesical ureteroneocystostomy technique without ureteral stenting in 500 consecutive kidney transplant recipients.

PLoS One 2021 11;16(1):e0244248. Epub 2021 Jan 11.

Department of Surgery, University of Miami Miller School of Medicine, Jackson Memorial Hospital, Miami, Florida, United States of America.

Urologic complications can still occur following kidney transplantation, sometimes requiring multiple radiological and/or surgical procedures to fully correct the problem. Previously proposed extravesical ureteral reimplantation techniques still carry non-negligible risks of the patient developing urologic complications. About 10 years ago, a new set of modifications to the Lich-Gregoir technique was developed at our center, with the goal of further minimizing the occurrence of urologic complications, and without the need for initial ureteral stent placement.

Hum Pathol 2021 Mar 8;109:53-58. Epub 2020 Dec 8.

Department of Pathology, Johns Hopkins Hospital, Baltimore, MD, 21287, USA; Department of Pathology, University of Alabama at Birmingham, Birmingham, AL, 35233, USA. Electronic address:

The spectrum of neuroendocrine (NE) tumors in the genitourinary tract ranges from the aggressive large and small cell carcinomas to the often benign paraganglioma and well-differentiated neuroendocrine tumor (WD-NET). At least 15 pure lower urinary tract (LUT) WD-NETs have been described. Owing to the rarity of WD-NET in the LUT and the limited number of reported cases, a better definition of their biologic long-term behavior is warranted. Read More

Transurethral Anastomosis after Transurethral Radical Prostatectomy: A Phantom Study on Intraluminal Suturing With Concentric Tube Robots.

IEEE Trans Med Robot Bionics 2020 Nov 29;2(4):578-581. Epub 2020 Oct 29.

Department of Mechanical Engineering, Vanderbilt University.

Current surgical approaches to radical prostatectomy are associated with high rates of erectile dysfunction and incontinence. These complications occur secondary to the disruption of surrounding healthy tissue, which is required to expose the prostate. The urethra offers the least invasive access to the prostate, and feasibility has been demonstrated of enucleating the prostate with an endoscope using Holmium laser, which can itself be aimed by concentric tube robots.
