BACKGROUND: Previously, we explored the histopathologic characteristics of medullary ray injury (MRI) inducing interstitial fibrosis and tubular atrophy (IF/TA) to determine its etiologies, which include calcineurin inhibitor (CNI) toxicity and urologic complications. However, we did not examine the effects of these etiologies on long-term kidney allograft prognosis, because biopsy timing differed among cases. AIM: We examined the influence of early MRI on kidney allograft prognosis using protocol biopsies taken within a 3-month time frame...

BACKGROUND: Living donor kidney is the main source of donor organs in low to middle income countries. We aimed to develop a living donor risk model that predicts graft and patient survival in an emerging economy. METHODS: We used data from the Sindh Institute of Urology and Transplantation (SIUT) database (n = 2,283 recipients and n = 2,283 living kidney donors, transplanted between 1993 and 2009) and conducted Cox proportional hazard analyses to develop a composite score that predicts graft and patient survivals...

Enteric drainage has been the main trend in solitary pancreas transplantation. Compared with bladder drainage, it does not cause metabolic or urologic complications, but there is no way to perform immunologic monitoring, except by graft pancreas biopsy. Additionally, although portal drainage of the graft vein is considered physiological drainage, it has more of a risk for surgical complications. To overcome these disadvantages, we successfully performed inferior vena cava (IVC)-duodenal drainage in pancreas alone transplantation...

En bloc pediatric transplantation (EBPT) began with the aim of increasing the donor pool due to the existing high demand for donors. At its inception, it was considered a type of suboptimal transplantation due to its association with a high incidence of vascular, urologic, and immunologic complications. The main objective of this study was to update information on EBPT with the largest case series that exists on a worldwide scale. In a retrospective study, the results obtained from brain-dead donors (BDDs; n = 770) were compared to those of EBPT (n = 100) from January 1990 to December 2012...

This study investigated the significance of urological surgical intervention for viral hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 1, 024 patients underwent allo-HSCT at our medical center between January 2006 and July 2014. In the 6 patients (0.58%) who required urological surgical treatment for viral HC, we retrospectively analyzed patient characteristics and outcomes. Two patients underwent nephrostomy for bilateral hydronephrosis due to bladder tamponade...

OBJECTIVE: To define clinical features of surgical patients in whom postoperative blood cultures are likely to identify pathogens. BACKGROUND: Bacteremia is a worrisome postoperative complication and blood cultures (BCx) are routinely used for evaluation of postoperative bacteremia, but are costly and not always diagnostic. Better methods are needed to select patients in whom BCx identify pathogens. METHODS: We reviewed records of patients ≥18 years old with BCx drawn ≤10 days after surgery in 2013 seeking independent predictors of positive cultures by simple and multiple logistic regression models with statistical significance at α = 0...

Urinary tract infections (UTI) are common in emergency departments (ED), and at least 15% of them are bacteremic. However, there are few data on how to predict which patients are at high risk of developing bacteremic UTI (b-UTI). We performed a retrospective observational cohort study including patients diagnosed with UTI who were admitted to the ED of a tertiary-care hospital in Spain. We included only those patients in whom blood cultures were performed. A nomogram for b-UTI was developed as visualizations of a logistic regression model...

Congenital anomalies of the inferior vena cava (IVC) are rare but important problems in living donors for kidney transplantation, especially in cases of a short left renal vein and accompanying vascular and urological anatomic variations. However, the clinical impacts of IVC anomalies in deceased donors have yet to be reported. The unexpected presence of an IVC in an unusual position poses challenges to surgeons and increases the risk of bleeding during organ removal. Accompanying vascular variations can cause unexpected bleeding and injury and therefore technical complications in procurement and subsequent implantation...

INTRODUCTION: As the nation's population ages and the number of practicing urologists per capita declines, characterization of practice patterns is essential to understand the current state of the urological workforce and anticipate future needs. Accordingly, we examined trends in adult inpatient urological surgery practice patterns over a five-year period. METHODS: We used the Nationwide Inpatient Sample (NIS) data from 2005 through 2009 to identify both surgeons and urological surgeries...

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...

Surgical complications (SCs) are still high potential causes of graft loss. The incidence has a huge amount of variations depending on many factors. Our aim was to study the postoperative technical complications following kidney transplantations (KTs) during a 5-year period between 2011 and 2015. In the observed time frame there were 47 SCs occurring in 32 (19.4%) patients of 165 KTs. Every complication was classified into 3 groups: vascular (11; 6.6%), urologic (16; 9.7%), and any others (20; 12.1%). The most common postoperative SCs in our center were hemorrhage (14; 8...
