Rare variant of renal vascularization with bilateral multiple pedicles and incomplete rotation - case report.

Rare variant of renal vascularization with bilateral multiple pedicles and incomplete rotation - case report. Rom J Morphol Embryol. 2019;60(3):1015-1018 Authors: Zăhoi DE, Sztika D, Stoican L, Dăescu E Abstract Renal blood vessels present great morphological variability. The routine dissection of a 68-year-old male cadaver revealed multiple bilateral vascular variations associated with the incomplete rotation of both kidneys. The left kidney was supplied by three renal arteries: one superior artery and one middle artery with hilum penetration, and one inferior artery with inferior polar penetration. All three arteries arose from the aorta: two from the anterior side at levels L1 and L3, and one - the inferior artery - from the posterior side of the aorta, as a common trunk with the middle sacral artery. The right kidney had two arteries, both arising from the aorta. The superior renal artery, arising at level L1, entered the renal parenchyma at the hilum; the inferior artery, arising at the point where the abdominal aorta branches in the two common iliac arteries, entered the parenchyma at the inferior pole. Each of the five arteries was accompanied by a vein. The (bilateral) superior renal veins and the middle left vein drained into the inferior vena cava. The two inferior renal veins joined to form a common trunk that drained into the left common iliac vein. Both kidneys presented incomplete rotation, each renal pelvis being situated anterior to the ...

Borgstrom, Daniel J. GraboAbstractBackgroundUse of minimally invasive techniques for management of common bile duct (CBD) stones has led to declining number of CBD explorations (CBDE) performed at teaching and non-teaching institutions. We evaluate the impact of this decline on surgery training in bile duct procedures.Study designNational operative data for general surgery residents (GSR) were examined from 2000 to 2018.

ConclusionWe found multiple heterogeneous predictors for SL with a common denominator related to surgical management of the retroperitoneal space, peritoneum and the ureter. Future prospective studies are necessary to evaluate the influence of these variables on the development of SL.

CONCLUSIONS: In selected cases, conservative management is a safe and feasible alternative to RNU, with the advantage of renal unit preservation. PMID: 28761590 [PubMed]

Conclusion Ureteral arterial fistula is a potentially life-threatening condition. Endovascular stenting has provided a safe, reliable alternative to open surgery. However, when endovascular options are not satisfactory, coil embolization of the ureteral stump may serve as a safe and effective alternative treatment for these cases.

Authors: Tugcu V, Atar A, Sahin S, Seker G, Kargi T, Tasci AI Abstract BACKGROUND AND OBJECTIVES: Our objective is to report intermediate-term outcomes for patients who have undergone upper tract urologic laparoendoscopic single-site surgery (LESS) at a single institution. METHODS: From January 1, 2008, through November 30, 2012, 107 cases treated with LESS were identified, including pyeloplasty (n = 30), ureterolithotomy (n = 32), nephrectomy (n = 35; simple = 31, partial = 4), and cyst decortication (n = 10). Perioperative data were reviewed, and conversion and complication rates were noted. RESULTS: The ...

CONCLUSIONS: Postoperative complications within 30 days of surgery are common after LNU and LRN. Despite having technical similarities, LNU carries a significantly higher risk of developing short-term complications compared to LRN. This information should be considered when counseling patients prior to surgery. Notable limitations of this study included the lack of information on tumour stage and management of the distal ureter. PMID: 27217860 [PubMed]

Conclusion Minilaparoscopy is a feasible option for patients and physicians searching for a even less invasive procedure compared with the laparoscopic approach, with better cosmetic and the same functional and oncologic outcomes.
