Allograft lithiasis is a rare urologic complication of renal transplantation (RT). Our aim is to present our experience with minimally invasive surgical treatment of allograft lithiasis in our series of live-donor renal transplant recipients. In a retrospective analysis of 3758 consecutive live-donor RTs performed in our center between November 2009 and January 2017, the results of minimally invasive surgery for the treatment of renal graft lithiasis diagnosed at follow-up were evaluated. Twenty-two (0.58%) patients underwent minimally invasive surgery for renal graft lithiasis...

With the recent introduction of more potent modern immunosuppressive regimens in solid-organ transplant, new types of viral infections such as adenovirus are emerging as a potential cause for graft dysfunction and loss. We report a case of 41-year-old male patient with end-stage renal disease from recurrent kidney stones who underwent kidney transplant from a deceased 12-year-old female donor. He developed adenoviral infection with acute cystitis, microscopic hematuria, and necrotizing interstitial nephritis associated with graft dysfunction within the first month of the postoperative period...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

OBJECTIVES: Urinary calculi rarely occur in renal transplant. However, because of peculiarities shown with renal allografts, a prudent approach is necessary to prevent further complications or even graft failure. There are no well-established guidelines for uro?ithiasis in renal grafts regarding adequate therapy selection. In the present article, different therapeutic interventions are discussed, including in 1 case a pyelovesicostomy as an uncommon intervention. MATERIALS AND METHODS: We retrospectively reviewed data of 1115 patients who underwent renal transplant between January 2002 and December 2014 for urolithiasis in different databases...

INTRODUCTION: Renal transplantation remains the gold standard treatment for end-stage renal disease, with living donor kidneys providing the best outcomes in terms of allograft survival. As the number of patients on the waitlist continues to grow, solutions to expand the donor pool are ongoing. A paradigm shift in the eligibility of donors with renal anomalies has been looked at as a potential source to expand the living donor pool. We sought to determine how many patients presented with anatomic renal anomalies at our transplant centre and describe the ex-vivo surgical techniques used to render these kidneys suitable for transplantation...

BACKGROUND: Enteric hyperoxaluria (EH) occurs with a rate of 5-24% in patients with inflammatory bowel disease, ileal resection and modern bariatric surgery. The excessive absorption of calcium oxalate causes chronic kidney disease (CKD) in patients with EH. In the literature, a single experience was reported in combined intestine-kidney transplantation (CIKTx) in patients with CKD due to EH. METHODS: After a report of 2 successful cases of CIKTx in patients with EH and CKD, one was performed at our center in a 59-year-old Caucasian female who developed intestinal failure with total parenteral nutrition (TPN) dependence after a complication post-bariatric surgery...

We report a rare case of nephrocalcinosis caused by hereditary renal hypouricaemia 3 months after kidney transplantation. A 41-year-old man who underwent living-related kidney transplantation from his father was admitted to our hospital for a protocol biopsy; he had a serum creatinine (S-Cr) of 1.37 mg/dL and no proteinuria. Histologically, there was no evidence of rejection or calcineurin inhibitor toxicity, although scattered nephrocalcinosis was observed in the distal tubules. Perioperatively, the patient had a serum uric acid (S-UA) of 1...

BACKGROUND: It is said that renal transplantation lithiasis is rare. However, literature has some different frequencies in this field and most of the studies related to this issue are case reports. Also the exact effect of this complication on the graft survival rate is not clear. OBJECTIVES: To determine the prevalence of nephrolithiasis among kidney transplant recipients and evaluate its association with the graft survival. METHODS: We conducted a retrospective study to determine the prevalence of renal stone among 574 kidney transplant patients aged ≥18 years who had undergone renal transplantation in Baqiyatallah Transplant Center between 1990 and 2010...

Percutaneous nephrolithotomy (PCNL) is an established safe and effective surgical treatment option for renal calculi in renal allografts. The advent of tubeless PCNL has led to reports of ambulatory or outpatient PCNL. This case report describes the successful outpatient management of a 49-year-old female with a symptomatic renal pelvic calculus in her transplanted kidney. Tubeless PCNL successfully removed the stone, free of complication, and the patient was discharged 2 hours and 17 minutes after the procedure in stable condition with minimal pain...

BACKGROUND: Knowledge of an optimal expected serum creatinine (SCr) would be useful to detect early renal dysfunction after transplantation. Current measurements of posttransplant function rely on the recipient's SCr and calculations of estimated glomerular filtration rate (eGFR), based on recipient age, weight, and sex. Renal function after transplantation, however, also depends on the donor supply of functioning nephrons and adaptation in GFR of a single kidney. METHODS: We developed a formula to predict the optimal expected SCr after transplantation derived from donor and recipient Cockroft-Gault GFRs and adjusted for the single kidney adaptive response...

Renal transplantation in recipients with an ileal conduit is uncommon and occasionally controversial as it has been associated with high morbidity and mortality rates. We report on 17 patients with an ileal conduit who received a deceased donor renal transplant at our institution between January 1986 and December 2012. We retrospectively reviewed their allograft and surgical outcome. There were four mortalities at five, five, 39, and 66 months post-transplant. Sixteen of 17 grafts functioned immediately; one patient had primary non-function secondary to vascular thrombosis...
