[Evaluation of ischemia-modified albumin in obstructive renal injury.]

Arch Esp Urol 2021 May;74(4):427-434

SBU Haydarpasa Numune SUAM. Department of Urology. Istanbul. Turkey.

Objectives: This study was aimed at assessing the ability of ischemia-modified albumin (IMA) to predict renal injury by associating biochemical, functional, and pathological findings with various degrees of ureteral obstruction.

Methods: Twenty-four rats were randomized into three groups, and their blood was sampled to determine the creatinine and IMA values and renal scintigraphy was done at the start and on postoperative day 7. In the sham group, the ureter was untouched; in the partial group, the ureter was gently embedded into the psoas muscle; and in the complete group, the ureter was compathologically, and all parameters were statistically evaluated.

Unilateral Obstructed Müllerian Anomalies: A Series of Unusual Variants of Known Anomalies.

J Pediatr Adolesc Gynecol 2021 Apr 25. Epub 2021 Apr 25.

The Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine, Weill Cornell Medical College, 1305 York Avenue, 6th Floor New York, New York 10021.

Background: Obstructed Müllerian anomalies in adolescents can be grouped into complete outflow obstruction or unilateral outflow obstruction. The challenge with unilateral obstructions is that diagnosis can be delayed for weeks to years as menstruation occurs normally through the patent side and thus obstruction is often not initially considered in the differential diagnosis.

Case: In this case series, we present three unusual and challenging cases of unilateral Müllerian obstructions in adolescent females along with strategies for diagnosis and management. Read More

Eur Urol 2021 Mar 5. Epub 2021 Mar 5.

University of Toronto, Department of Radiation Oncology, 149 College Street, Unit 504, Toronto, Ontario, M5T 1P5, Canada; Radiation Medicine Program, Princess Margaret Cancer Centre, University Health Network, 700 University Avenue, 7th floor, Toronto, Ontario, M5G 1Z5, Canada; TECHNA Institute, University Health Network, University of Toronto, 200 Elizabeth Street, Toronto, Ontario, M5G 2C4, Canada. Electronic address:

Background: The hypothesis of a curable oligometastatic prostate cancer (PCa) state remains to be clinically-proven. Conventional imaging often fails to localize early recurrences, hampering the potential for radical approaches.

Objective: We hypothesize that prostate-specific membrane antigen (PSMA)-targeted PET-MR/CT allows for earlier detection and localization of oligorecurrent-PCa, unveiling a molecularly-defined state amenable to curative-intent metastasis-directed treatment (MDT). Read More

Kidney organoids: Research in developmental biology and emerging applications.

Dev Growth Differ 2021 Feb 21;63(2):166-177. Epub 2021 Mar 21.

Center for iPS Cell Research and Application (CiRA), Kyoto University, Kyoto, Japan.

Kidney organoids generated from human pluripotent stem cells (hPSCs) have drastically changed the field of stem cell research on human kidneys within a few years. They are self-organizing multicellular structures that contain nephron components such as glomeruli and renal tubules in most cases, but hPSC-derived ureteric buds, the progenitors of collecting ducts and ureters, can also form three-dimensional organoids. Today's challenges facing human kidney organoids are further maturation and anatomical integrity in order to achieve a complete model of the developing kidneys and ultimately a complete adult organ.

J Clin Med 2021 Jan 23;10(3). Epub 2021 Jan 23.

Department of Women and Children's Health, Clinic of Gynecology and Obstetrics, University of Padua, 35121 Padua, Italy.

Ultrasound is an effective tool to detect and characterize lesions of the uterosacral ligament, parametrium, and paracervix. They may be the site of diseases such as endometriosis and the later stages of cervical cancer. Endometriosis and advanced stages of cervical cancer may infiltrate the parametrium and may also involve the ureter, resulting in a more complex surgery. Read More
