BACKGROUND: Kidney transplantation (KT) is the treatment option for patients with end stage renal disease (ESRD) to prolong survival and improve quality of life. Although the use of potent immunosuppressive agents increases graft survival in kidney transplantation recipients (KTRs), it may lead to the development of malignancy, including transitional cell carcinoma (TCC). TCC developing in the pelvis of graft kidney is very rare in KTRs. CASE PRESENTATION: A 40-year-old male visited hospital with complaints of nausea, vomiting and gross hematuria...

During the time of organ harvest, it is crucial for the kidney procurement team to consider significant vascular anatomical variations. Multiple renal arteries are not uncommon, and unintentional injury can result in an irreversibly damaged kidney graft that needs to be discarded. We present a kidney graft with 5 renal arteries and a single vein that was successfully procured and implanted with good graft function at discharge and at 4-yr follow-up. According to the literature, additional renal arteries can be found in about 33% of kidneys...

Ju Yong Cheong, Christopher J Young
PURPOSE: Hand-assisted laparoscopic surgery (HALS) is a minimally invasive surgical technique with the combined benefits of laparoscopic surgery while allowing the use of the surgeon's hand for better tactile control. Obesity has been associated with higher conversion rates with multiport laparoscopic surgery, but not with HALS. This study aimed to examine the versatility of HALS in various clinical contexts. METHODS: All HALSs performed at 2 major tertiary centers in Sydney were prospectively collected for retrospective analysis...

Ferzine Mohamed, Susan Jehangir
Congenital anomalies of the kidney and urinary tract (CAKUTs) occur in 3-6 per 1000 live births, accounting for most cases of paediatric end-stage kidney disease.(1) However, the molecular basis of CAKUT and anomalies of the external genitalia is poorly understood. We, herein, describe a case with left recurrent epididymo-orchitis with a coexistent urethral duplication and an ectopic ureter with an ipsilateral non-functioning kidney, which is, to the best of our knowledge, the first reported case of its kind...

BACKGROUND: We describe a simple and reliable orthotopic kidney transplantation method in rats with the use of sleeve arterial anastomosis and a modified stenting technique for anastomosis of the renal vein (RV). METHODS: Male Fischer and Lewis rats were used as kidney donors and recipients, respectively, and their left kidneys were harvested in situ. In the control rats (n = 30), the renal artery (RA) and RV anastomoses were performed end-to-end with interrupted sutures by means of the conventional technique...

Perviz Hajiyev, Berk Burgu
CONTEXT: Vesicoureteral reflux (VUR) remains the most interesting topic of pediatric urology due to the dynamic nature of recent controversial publications. Starting from the need for a diagnosis to the necessity and effectiveness of treatment in preventing scars, VUR remains in the mist. Although recent strong evidence helped as fog lights in this blurriness, more data are required for achieving crystal clearance. This article aims to summarize and discuss the current state of the evidence regarding VUR management...

We experienced a rare case of primary leiomyosarcoma of sigmoid mesentery. A 45-year-old woman was presented to us with left iliac fossa mass and discomfort for 4-month duration. CT scan of abdomen and pelvis revealed a huge mass 14 cm×14 cm×16 cm occupying left iliac fossa mimicked having a large left ovarian carcinoma. She was subsequently planned for elective total abdominal hysterectomy and bilateral salpingo-oophorectomy by gynaecology team. During laparotomy, a huge mass was revealed arising from sigmoid mesentery invaded to the left lower ureter...

Objective: The rate of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma is high. Seeding upper urinary tract urothelial carcinoma cells onto the damaged bladder wall is considered to be one of the causes of intravesical recurrence after radical nephroureterectomy. We evaluated the utility of early ureteral ligation in preventing the intravesical recurrence. Methods: This prospective single-arm clinical trial included patients who underwent radical nephroureterectomy for upper urinary tract urothelial carcinoma in the Tohoku Urological Evidence-Based Medicine Study Group between 2012 and 2013...

REVIEW
Mohamed A Elkoushy, Sero Andonian
Patients presenting with nephrolithiasis often undergo repeated imaging studies before, during, and after management. Considering the significant risk of stone recurrence in primary stone-formers, repeated imaging studies are not uncommon. Cumulative effects of ionizing radiation exposure from various imaging studies could potentially increase the risk for developing cataracts and solid malignancies in urolithiasis patients. Therefore, practitioners planning or performing imaging studies with ionizing radiation are compelled to keep radiation exposure to humans and the environment as low as possible, thus strictly adhering to the ALARA (As Low as Reasonably Achievable) principles...

Background: Ureter involvement within indirect hernias is a rare phenomenon usually identified incidentally during herniorrhaphy. Even more rare are extraperitoneal ureteral inguinal hernias, which represent about 20% of these cases and are characterized by a substantial amount of extraperitoneal fat in the hernia defect, the absence of a peritoneal sac, and associated with hydroureteronephrosis and nephroptosis. To date, repair of ureteral inguinal hernias has been performed exclusively using open surgical techniques...

Urolithiasis is a well-known and common late complication in patients with urinary diversion. Patients without urinary diversion lead to symptoms such as hematuria and ureteral colic, whereas stones in patients with urinary diversion tend to be asymptomatic and are often diagnosed incidentally during staging examinations of oncologic diseases. We report the case of a 64-year-old male patient with a lower pole kidney stone and a stone in the ileal ureter substitution. He presented with diffuse abdominal and left-sided flank pain...

Showkathali Iqbal, Iqbal Raiz, Iqbal Faiz
Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex...

The ureterocele is an uncommon congenital anomaly of the lower ureter. Ureterocele with a single pelvicalyceal system, bilateral, and orthotopic variety is less common. Calculi within bilateral ureterocele are a rare occurrence. To the best of our knowledge, only a few similar cases have been reported in the literature. Among the all reported presentations of this type of ureterocele, presentation with Acute Urinary Retention (AUR) has not been described in the literature. We present a case of nine-year-old child having bilateral, single system orthotopic ureterocele with calculi in bilateral ureterocele and presented with AUR due to obstructive bulbar urethral calculus...
