Our Pediatric Liver and Kidney Transplant Activities in 2021.

Exp Clin Transplant 2022 May;20(Suppl 3):85-88

From the Baskent University, Department of General Surgery, Division of Transplantation, Ankara, Turkey.

Objectives: In children with end-stage renal disease, chronic liver failure, or acute liver failure, liver transplant and kidney transplant are the most effective modalities for better clinical outcomes compared with other therapies. However, children are particularly susceptible to surgical complications, so pediatric solid-organ transplants should be reserved for centers with substantial experience and multidisciplinary expertise.

Acute effect of sacral neuromodulation on video-urodynamic parameters of neurogenic lower urinary tract dysfunction in a patient with vesicoureteral reflux: a case report.

Ann Palliat Med 2022 Apr;11(4):1568-1574

Department of Urology, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, China; Beijing Hospital Continence Center, Beijing, China.

Neurogenic lower urinary tract dysfunction (NLUTD) is a common urological disease that causes long-term complications and severely reduces patient's quality of life. Sacral neuromodulation has proven to be an effective treatment for NLUTD. However, most previous studies have focused mainly on the efficacy and safety of sacral neuromodulation in the treatment of NLUTD and less on the changes in urodynamic parameters in patients before and after sacral neuromodulation.

Authors:
Karl-Heinz Deeg

Ultraschall Med 2022 Apr 29. Epub 2022 Apr 29.

Pediatric Clinic, University of Erlangen/Nuremberg, Erlangen, Germany.

Duplex kidneys have two renal pelvises and two ureters, which can join on the way to the urinary bladder but can also enter the bladder separately. A distinction must be made between normal and pathological duplex kidneys. In normal duplex kidneys, both renal pelvises are normal in width, and the upper and lower poles are approximately the same size. Read More

[Bradis anti-reflux ureterocysto-anastomosis in children with recurrent obstructive megaureter].

Urologiia 2022 May(2):5-10

Rostov State Medical University of the Russian Federation Ministry of Public Health, Rostov-on-Don, Russia.

Introduction: Congenital ureterovesical junction (UVJ) obstructions quite rarely serve as an indication for ureteral reimplantation, and recurrent obstructions resulting from surgical treatment are even less frequent. Cases of acquired UVJ obstruction following endoscopy and ureteral reimplantation done for vesicoureteral reflux correction are fairly rare. The lack of known publications analyzing treatment of recurrent obstructive megaureter predetermines topicality of our research. Read More

The safety cutoff storage pressure for preventing upper urinary tract damage in neurogenic bladder from spinal cord pathology and risk factor analysis.

Neurourol Urodyn 2022 04 23;41(4):991-1001. Epub 2022 Mar 23.

Department of Surgery, Division of Urology, Thammasat University Hospital, Pathum Thani, Thailand.

Introduction: Low-compliance bladder or high bladder pressure undoubtedly leads to hydronephrosis and renal impairment. As four decades have elapsed since a previous study found a detrusor leak-point pressure (DLPP) >40 cm H O to result in hydronephrosis, we suspected the possibility of hydronephrosis or vesicoureteral reflux occurring at any point below the 40 cm H O DLPP reference. Therefore, this study aimed to determine the storage detrusor pressure value and risk factors related to upper urinary tract damage (UUTD). Read More
