BACKGROUND: Page kidney phenomenon is caused by strong renal parenchymal compression and leads to renal hypoperfusion and microvascular ischemia, resulting in renal dysfunction and hypertension. Although the development of Page kidney phenomenon in allograft is rare, most of its cases are induced by allograft biopsy or trauma. We observed a case of Page kidney phenomenon that was induced by unusual causes immediately after kidney transplantation. CASE PRESENTATION: A 66-year-old man, whose wife donated a kidney, underwent ABO-compatible living kidney transplantation...

Urinary tract involvement by endometriosis is reported in 1% of endometriosis patients (NP3). Consequences range from pelvic pain for bladder localizations to silent kidney loss in case of chronic ureteral obstruction (NP3). The feasibility of laparoscopic management was widely proven (NP3) and may reduce hospital stay length (NP4). Radical surgery with partial cystectomy for bladder localizations was shown to significantly and durably reduce pain symptoms with low risk of a severe postoperative complications (NP3)...

We report a case of a highly advanced urothelial carcinoma accompanied by duodenal stenosis with pancreaticoduodenectomy. A6 6-year-old man presented with upper abdominal pain and vomiting. Acute pancreatitis and hydronephrosis were diagnosed with urgent hospitalization, but jaundice appeared, and stenosis of the duodenum was also found. Thus, we suspected groove pancreatitis or pancreatic cancer, and performed pancreaticoduodenectomy. However, poorly differentiated adenocarcinoma was observed in the retroperitoneal dissection surface in the intraoperative rapid tissue and right hemicolectomy, right nephrectomy, and right ureteral resection were added to the diagnosis...

Background: Ureteral strictures are a recurrent chronic condition that leads to severe side effects and poor quality of life. Management of ureteral stricture is a great challenge for urologists and no specific guidelines exist. Retrograde Allium® ureteral stent (AUS) is a newly developed ureteral stent to treat either bulbar urethral or ureteral stenosis. Case Presentation: We describe a case of a 74-year-old Caucasian adult male presenting with a severe ureteral stricture secondary to an ureteroscopy for stone disease...

Ureteral stents are routinely used in renal transplant and are associated with reduced urological complications but increased urinary tract infections (UTIs). There is no agreement on the preferred time to removal of stents after transplantation. We performed a systematic review and meta-analysis of all randomized controlled trials (RCTs) comparing stent duration of <14 days vs > =14 days. Electronic databases were searched to identify RCTs that compared early vs late stent removal. Primary outcome was urinary tract infections...

Ureterosigmoidostomy has largely been disregarded in recent times but has now seen a resurgence of interest because of its potential applicability to newer, minimally-invasive surgical techniques. The advantages of ureterosigmoidostomy over intestinal conduits are urinary continence (obviating the need for stoma and external appliances), ease and rapidity of performance as well as acceptance by patients. Ureterosigmoidostomy has been characterized by good continence outcomes and it offers good quality of life...

OBJECTIVE: Prenatal ultrasound (US) screening detects the hydronephrosis (HN)-dilatation of fetal renal collecting system in 1%-5% of all pregnancies. In most children, HN is detected by prenatal US screening between 18-20 gestational week. Pelvi- ureteric junction (PUJ) stenosis is the most common etiological factor of prenatal HN and requires postnatal follow-up. Diuresis renography plays important role in the follow-up by complementing morphological information obtained by US with the data about differential renal function (DRF) and drainage...

We have developed the Peralta Stone Extraction System to increase the safety of ureteral stone extraction. The device combines a nitinol stone basket and low-pressure balloon into a single device. After visualization, the stone is captured in the tipless nitinol basket and enveloped by a low-pressure balloon. We tested the performance of device prototypes in a porcine model using stone mimics with diameters ranging from 4.2 to 6.2 mm. Stones extracted with the device required less force when compared with stones in a standard ureteral stone basket...

In recent years, the frequency of high-risk kidney transplantations has increased. We report a case in which a 72-year-old man with various severe comorbidities (prostate cancer, diabetes mellitus, complete atrioventricular block, coronary artery stenosis, severe stenosis of the popliteal arteries, and severe calcification of the iliac arteries) who received an orthotopic kidney transplantation. To prevent the occurrence of acute limb ischemia due to the steal phenomenon (caused by the kidney graft), we decided that a heterotopic kidney transplantation involving the iliac arteries was not an appropriate option...

In aggressive cases, endometriosis can perturb the urogenital tract, in particular the ureter, which can potentially result in ureteral compression or stenosis. Even though this is rare, consequences are dramatic, such as hydronephrosis or organ failure. The present standard intervention comprises the resection of affected tissues and endometriosis foci combined with adjuvant hormonal therapy. When the ureter does not recover, ureteral reimplantation is required. The present case describes the successful laparoscopic approach of the reimplantation of the ureter with simultaneous cystoscopy...

Background: The obstructive hydronephrosis is a term that implicates the structural and functional changes of the kidneys as a result of difficulties in the flow of urine. Hydronephrosis specifically describes dilation and swelling of the kidney. Hydronephrosis is a condition that typically occurs when the kidney swells due to the failure of normal drainage of urine from the kidney to the bladder. Our aim was to evaluate the degree of hydronephrosis, causes and diagnostic method. Material and...

INTRODUCTION: Repair of long ureteral defects often requires long graft tissues and extensive surgery. This is associated with complications including a lack of suitable tissue and graft site morbidity. Tissue engineering may provide an attractive alternative to the autologous graft tissues. In this study, ureteral repair using (pre-implanted) tubular collagen-Vicryl templates was evaluated in a new goat model. MATERIALS AND METHODS: Tubular templates were prepared from tubularized Vicryl meshes and 0...

BACKGROUND: Reconstruction of ureteral defects and strictures remains problematic for urologists. We aimed to investigate the possibility of a tapered non-vascularized bladder graft as a novel substitute for ureteral reconstruction. METHODS: This experimental study was conducted on nine beagles. Under general anesthesia, a full-thickness graft with 5-6 cm in length was disassociated from the anterior upper wall of the bladder, and tapered into 1/3 to 1/2 thickness, remaining the urothelial surface...

We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus...

PURPOSE: Bladder cancer (BC) may involve the ureteral orifice, and the resection of the orifice has oncological and functional consequences such as development of upper tract urothelial carcinoma (UTUC), vesicoureteral reflux or ureteral stenosis. The aim of this study was to investigate the oncological and functional outcomes of the ureteral orifice resection in BC patients and determine the predictive factors for UTUC development. MATERIALS AND METHODS: A total of 1359 patients diagnosed with BC, between 1992 and 2012, were reviewed retrospectively...
