Use of retrograde pyelogram to plan for miniature open incision in pediatric pyeloplasty.

J Pediatr Urol 2020 Apr 30. Epub 2020 Apr 30.

Division of Pediatric Urology, Riley Hospital for Children at IU Health, 705 Riley Hospital Dr., Suite 4230, Indianapolis, IN, 46202, USA. Electronic address:

Introduction: As robotic-assisted surgery becomes increasingly utilized for pediatric ureteropelvic junction (UPJ) obstruction, open surgeons have countered by using muscle-splitting, miniature (≤2 cm) incisions. To prepare for this type of incision during pyeloplasty, it is necessary to define the exact location of the UPJ. The use of retrograde pyelogram (RPG) at the time of pyeloplasty helps the surgeon to identify the exact location of UPJ, and thus be able to use a muscle-splitting, miniature incision for open pyeloplasty.

Community Acquired Urosepsis: A surgical intensive care Experience.

Qatar Med J 2020 2;2020(1). Epub 2020 Apr 2.

Chief Medical Officer, Hamad Medical Corporation, Doha, Qatar.

Urosepsis contributes significantly to the epidemiology of sepsis. Urosepsis can be classified as community acquired or hospital acquired, depending upon the origin of infection acquisition: either from the community or from a healthcare facility. A great deal of literature is available about nosocomial urosepsis, but the literature regarding community-acquired urosepsis (CAUs) is limited, and studies are underpowered. Read More

Percutaneous nephrolithotomy for staghorn calculi: Troubleshooting and managing complications.

Asian J Urol 2020 Apr 19;7(2):139-148. Epub 2019 Oct 19.

Department of Urology, University of California, Oakland, CA, USA.

Staghorn calculi comprise a unique subset of complex kidney stone disease. Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for staghorn stones. Despite continuous refinements to the technique and instrumentation of PCNL, these stones remain a troublesome challenge for endourologists and are associated with a higher rate of perioperative complications than that for non-staghorn stones.

Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei 430030, P.R. China.

Percutaneous nephrolithotomy (PCNL) has become a routine surgical procedure for treating patients with large kidney stones; the fundamental step in this process is the creation of the nephrostomy tract. In the present study, a meta-analysis was performed to compare the effectiveness and safety of different tract dilation techniques for PCNL. Databases were searched from inception to 1 April 2019 to identify relevant randomized controlled trials. Read More

Papillary vs non-papillary access during percutaneous nephrolithotomy: Retrospective, match-paired case-control study.

Arch Ital Urol Androl 2020 Apr 6;92(1):50-52. Epub 2020 Apr 6.

Department of Urology, Health Sciences University, Umraniye Teaching Hospital, Istanbul.

Objective: The most crucial steps of percutaneous nephrolithotomy (PCNL) are the percutaneous access and dilation of the access route. Recent literature suggests that papillary access to renal calyx is the accepted method. Despite this rule, we do not always make papillary puncture and we puncture wherever we can to achieve stone-free status and reduce unnecessary access. Read More

Management and treatment options when facing malignant ureteral obstruction.

Int J Urol 2020 Jul 6;27(7):591-598. Epub 2020 Apr 6.

Smith Institute for Urology, New Hyde Park, New York, USA.

Malignant ureteral obstruction is an unfortunate finding that can be caused by a wide-ranging number of malignancies with a prognosis of limited survival. Given its presentation and progression, it can be refractory to treatment by traditional single polymeric ureteral stents. With a higher failure rate than causes of benign ureteral obstruction, a number of other options are available for initial management, as well as in cases of first-line therapy failure, including tandem stents, metallic stents, percutaneous nephrostomies and extra-anatomic stents.
