Buccal mucosa graft for the treatment of long ureteral stenosis: Bibliographic review.
CONCLUSIONS: The findings of the present review do not justify the universal use of BMG in all ureteral strictures, particularly in the absence of long-term followup, but still provide evidence that BMG can be effectively used in extensive ureteral strictures. PMID: 28530624 [PubMed - in process]
Ureteral-arterial fistulas are a rare and life-threatening source of hematuria. They are caused by inflammatory and fibrocystic changes that become erosive defects between the ureter and adjacent iliac arteries. They occur more frequently in women and are associated with pelvic irradiation, ureteral and arterial manipulation, malignant disease, and pelvic or abdominal surgery. Here we describe one case and review five cases of endovascular repair.
This study presented extensive experience with vesicoscopic ureteral reimplantation (VR) for primary reflux. In this procedure, cross-trigonal reimplantation was performed in a manner analogous to open repair under carbon dioxide ‘pneumovesicum’.
Conclusions Uterosacral ligament suspension is a safe and effective procedure in primary surgical treatment of pelvic organ prolapse. Anatomical, functional, and subjective outcomes were very satisfactory, and reoperation rate for recurrence was only 1%.
Two distinct macrophage phenotypes contribute to kidney injury and repair during the progression of renal interstitial fibrosis; proinflammatory (M1) and antiinflammatory (M2) macrophages. Legumain, an asparaginyl endopeptidase of the cysteine protease family, is overexpressed in macrophages in some pathological conditions. However, the macrophage subtype and function of macrophage-derived legumain remains unclear. To resolve this we tested whether M2 macrophages contribute to the accumulation of legumain in the unilateral ureteral obstruction model.
Abstract En bloc kidney transplants of small pediatric kidneys into adult recipients have been shown to have outcomes similar to transplants from standard adult deceased donors. Here, we report a 27-year-old male patient with successful repair of bilateral ureteral stricture 3 years after en bloc kidney transplant at the Shahid Modarres Hospital (Tehran, Iran). The patient received an en bloc deceased kidney donation from a 9-month-old infant. An end-to-end anastomosis of the aorta to the internal iliac artery and an end-to-side external iliac vein anastomosis to vena cava were performed. At an outpatient visit ab...
Plasminogen activator inhibitor-1 (PAI-1) expression is highly upregulated in tubular and interstitial cells during obstructive uropathy (i.e., nephrolithiasis, ureteral stricture) and is linked to kidney fibrosis. Precise mechanisms whereby PAI-1 contributes to renal injury, however, are unknown and, surprisingly, appear to be urokinase-type plasminogen activator independent. Here, we test the hypothesis that sustained PAI-1 expression in renal epithelial cells promotes renal tubular dysfunction and maladaptive repair critical for chronic kidney disease progression.
Correct orientation of ureteric spatulation, and prevention of twisting of the ureter, may make laparoscopic dismembered pyeloplasty a challenging procedure. In this video we presented the technique of laparoscopic in situ dismembered pyeloplasty as a modified technique during which the alignment of ureter and renal pelvis remains intact during ureteropelvic junction (UPJ) anastomosis. We also assessed intraoperative and postoperative outcomes of this modification in comparison to standard laparoscopic dismembered pyeloplasty.
Ureteroenteric anastomotic stricture (UES) is a common long-term complication of urinary diversion occurring in up to 10% of patients. While open UES revision remains the gold standard, it is technically challenging and can be associated with visceral and vascular related injuries. In select cases, a minimally invasive surgical approach utilizing near-infrared laser fluorescence (NIRF) technology (Firefly ®) combined with antegrade ureteroscopy may allow for enhanced UES identification and ureter viability assessment.
We report a case of a 51-year-old female who suffered an iatrogenic 15 centimeter right ureteral avulsion during hysteroscopic biopsy who was managed with a robotic right appendiceal interposition and lower pole appendicocalicostomy.
Infants and children with obstruction or structural weakness of the uretero-vesical junction (UVJ) may require surgical repair. Re-implantation of a dilated ureter into a small capacity and/or scarred bladder following failed surgery, can represent a major surgical challenge. Herein a report on the outcome of the cuff-nipple method of ureteroneocystotomy in these difficult cases.
