Tubular Ectasia in Renal Allograft Biopsy: Associations With Occult Obstructive Urological Complications

Conclusions. TE together with additional signs of ATI indicates occult UOC. This histological phenotype should trigger more detailed evaluation for UOC when there is no evidence of relevant hydronephrosis in the ultrasonography.

Conclusion Inguinal herniation of the transplant ureter leading to ureteral obstruction is a rare, probably underreported, cause graft of dysfunction. Therefore, we advocate elective repair of inguinal or incisional hernias in renal transplant recipients. PMID: 31690216 [PubMed - as supplied by publisher]

We present the case of a 46-year-old man who underwent successful antegrade ureteroscopy for lithiasis in his allograft ureter. At a scheduled follow-up 15  years after transplantation, computed tomography (CT) detected a 12-mm renal stone in the renal pelvis of the transplanted kidney. During his follow-up, gross hematuria was seen; the stone moved to the ureter, causing hydronephrosis. Ultrasound and non-contrast CT revealed hydronephrosis and a 15- mm stone in the transplanted ureter. Considering the stone size, location, and the difficulty of the access to the anastomosed ureteral orifice, percutaneous ureteroscop...

Baranski AG Abstract Simultaneous pancreas-kidney transplant is the ultimate therapy for patients who have uncontrolled and complicated type 1 diabetes mellitus with end-stage renal disease. The combined pancreas transplant provides a euglycemic milieu for the kidney and protects it from recurrence of diabetic complications. Our patient, a 41-year-old woman with end-stage diabetic nephropathy and history of multiple abdominal surgeries (ovarian cyst fenestration, adnexal extirpation, abdominal wall reconstruction), including urinary diversion (Bricker loop, above double J stent), underwent simultaneous pancreas-ki...

Abstract Urolithiasis is a rare complication after kidney transplant. Over the years, treatment of kidney stones has evolved radically, but a standard approach for transplanted kidneys has not yet been defined. Here, we present a 69-year-old male patient who received successful treatment of nephrolithiasis of the transplanted kidney. The patient, who had received a kidney from a deceased donor, was admitted to our department following a posttransplant Doppler ultrasonography showing severe hydronephrosis of the transplanted kidney associated with acute renal function decay. Computed tomography scan confirmed the h...

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...

​BY NOURA MAHDI; DARRON LEWIS; JEREMY OSBORNE; &AHMED RAZIUDDIN, MDA 73-year-old man was brought to the emergency department from his nursing home for rectal bleeding and anemia. The patient mentioned he had had episodes of bright red rectal bleeding and constipation for a few months. A colonoscopy had been done prior to the visit, which revealed a large intestine tumor and biopsy confirming adenocarcinoma. He was awaiting an appointment with his surgeon.The patient reported bloody rectal leakage, and a CBC done at the nursing home showed a hemoglobin level of 7.2. He also complained of dyspnea but denied any other s...

An 82-year-old man with a history of renal transplantation 14 years earlier presented with acute obstructive renal failure secondary to inguinal herniation of the urinary bladder complicated by ureteroneocystostomy entrapment. After percutaneous nephrostomy tube and endoscopic stent placement, the bladder was reduced and the hernia repaired with the use of a preperitoneal mesh. The postoperative course was uneventful and the renal function returned to normal. Inguinal herniation of the transplant ureter is a rare cause of hydronephrosis, but it has been described in the literature.

Abstract OBJECTIVES: The most common complications after renal transplant are urologic and are a cause of significant morbidity in a vulnerable population. We sought to characterize the timing and predictors of urologic complications after renal transplant using a statewide database. MATERIALS AND METHODS: We queried the New York Statewide Planning and Research Cooperative System database to identify patients who underwent renal transplant from 2005 to 2013. Postoperative complications included hydronephrosis, ureteral stricture, vesicoureteral reflux, nephrolithiasis, and urinary tract infections. Cox propor...

Abstract: Acute renal failure due to ureter compression after a mesh-plug inguinal repair in a kidney transplant recipient has not been previously reported to our knowledge. A 62-year-old man, who successfully underwent kidney transplantation from a deceased donor 6 years earlier, was admitted for elective repair of a direct inguinal hernia. The patient underwent an open mesh-plug repair of the inguinal hernia with placement of a plug in the preperitoneal space. We did not observe the transplanted ureter and bladder during dissection of the inguinal canal. Immediately after surgery, the patient became anuric, and a graft s...

We describe a KT patient with BKVN without detectable BK viremia. A 62-year-old female with hypertensive nephropathy underwent renal transplant from a living relative donor in December 2011. Fourteen months after transplantation, her serum creatinine(SCr) rose up from 1.2 to 1.6 mg/dl with biopsy-proven acute antibody-mediated and cellular rejection. After pulse methylprednisolone, plasmapheresis and intravenous immunoglobulin, her SCr decreased to baseline but she subsequently developed cytomegalovirus infection with pancytopenia and transaminitis. The SCr rose to 1.9 mg/dl despite ganciclovir treatment. Renal ultrasound ...
