As the number of kidney transplants continues to rise, so does the number and complexities of surgical-related complications, which may be associated with increased morbidity and potentially graft loss. Ureteral stenosis, the most prevalent urological complication, may require diverse techniques for surgical correction depending on several recipient and graft abnormalities. Here we report the surgical and clinical outcomes of a 62-year-old man with a postransplant pyeloureterostomy stricture successfully treated with ureterocalycostomy after a lower pole nephrectomy...

PURPOSE: To evaluate the influence of overnight ureteral catheterization and determine if routine long-term post-stenting can be avoided in flexible ureterorenoscopy (fURS) procedure for kidney stone. METHODS: Three hundred ninety-three patients who underwent single fURS for kidney stone between January 2013 and June 2016 at a single institute were retrospectively analyzed. The stone-free (SF) and perioperative complication rates in patients with routine long-term post-stenting after fURS (long-term stent group) were compared with those of patients with overnight ureteral catheterization (short-term stent group)...

Urinary ascites is most commonly seen in fetuses and newborns with obstructive uropathy. The majority of cases are associated with lower urinary tract obstruction, such as posterior urethral valves. In this report, we present a unique case of neonatal urinary ascites caused by congenital supravesical obstruction. To date, neonatal urinary ascites secondary to bilateral mid-ureteral stenosis without a history of antenatal diagnosis has not been reported.

INTRODUCTION: Ureter stenosis in renal transplantation patients is a relatively frequent complication that negatively conditions graft evolution. The use of ureteral stents is a valid treatment alternative to the use of double-J catheters in patients for whom surgery is not contemplated or after surgical recurrence. We present our initial experience with five patients treated using this technique. MATERIALS AND METHODS: We describe a total of five patients with ureteral stenosis after renal transplantation who were treated using ureteral stent model UVENTA (Taewoong Medical, Seoul, Korea) in our center...

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...

REVIEW
Mikolaj Przydacz, Jacques Corcos
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...
