Antegrade endoscopic dilatation as an alternative approach to primary obstructive megaureter.

Cir Pediatr 2021 Apr 1;34(2):100-104. Epub 2021 Apr 1.

Interventional Radiology Department. La Paz University Hospital. Madrid (Spain).

Objectives: Congenital primary obstructive megaureter (POM) is caused by ureterovesical junction stenosis, reduced peristalsis, and the resulting dilatation. Even though ureteral re-implantation remains the current gold standard technique, retrograde dilatation is considered as an effective therapeutic alternative with good results and growing proponents - to the extent it has become the technique of choice in some healthcare facilities. The objective was to present an alternative approach for treatment purposes. Read More

Life-threatening abdominal compartment syndrome as a complication of supine super mini percutaneous nephrolithotomy, the first case report and literature review.

Urol Case Rep 2021 May 19;36:101578. Epub 2021 Jan 19.

Department of Urology, Hamad Medical Corporation, Doha, Qatar.

Abdominal compartment syndrome is a life-threatening complication of conventional percutaneous nephrolithotomy (PCNL), with few cases reported in different positions. We present the first case of abdominal compartment syndrome as a complication of supermini percutaneous nephrolithotomy (SMP) in The Galdakao-modified supine Valdivia position, possibly predisposing factors, diagnosis, and management. Although it is a challenging diagnosis and life-threatening condition, morbidity and mortality can be decreased with early detection and drainage of the intra-peritoneal fluid, causing increased abdominal pressure, which is the most important prognostic factor.

Efficacy of the Endoscopic Combined Intrarenal Surgery for the Treatment of a Staghorn Calculus in Crossed Fused Renal Ectopia.

J Endourol Case Rep 2020 17;6(3):205-208. Epub 2020 Sep 17.

Department of Urology, Cottolengo Hospital of Torino, Torino, Italy.

Crossed fused renal ectopia (CFRE) is an unusual anomaly in which both kidneys lie fused on one side, with double pelvis and ureters draining into both sides of the bladder. Complex renal stones are a considerable challenge to endourologists, and when a staghorn stone is associated with abnormal anatomy, its treatment is even more difficult. Today there is no consensus about the right treatment for complex renal stones in CFRE. Read More
