Congenital anomalies of the kidney and urinary tract (CAKUT) are the most common cause (40-50%) of chronic kidney disease (CKD) in children. About 40 monogenic causes of CAKUT have so far been discovered. To date less than 20% of CAKUT cases can be explained by mutations in these 40 genes. To identify additional monogenic causes of CAKUT, we performed whole exome sequencing (WES) and homozygosity mapping (HM) in a patient with CAKUT from Indian origin and consanguineous descent. We identified a homozygous missense mutation (c...

The embryological development of the inferior vena cava (IVC) is complex, and thus the vena cava may undergo a large number of congenital anomalies. Periureteric venous ring is a rare developmental anomaly of IVC where the right ureter passes through a slit-like opening in a partially duplicated infrarenal IVC, resulting in dilatation of upper urinary tract. Split-bolus multidetector computed tomography technique is useful in detecting such vascular anomaly causing ureteric obstruction as it can clearly show the vascular and ureteric phase in a single acquisition...

BACKGROUND: Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. METHODS: All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset...

We present the first case of patients with more than 15 years forgotten ureteral stents. A 68-year-old woman affected by cervical cancer, who underwent a radical hysterectomy in 1997 and reported a placement of bilateral ureteral stents. She was admitted in our Hospital for stranguria, dysuria, and lower back pain for 10 days. Preoperative radiological evaluation showed the persistence of ureteral stents. She never removed the stent which had been positioned for a long period of time(since 1997). We proceed to remove in general anaesthesia bilateral stents by urethral cystoscopic...

Intravesical recurrence (IVR) after RNU for UTUC is a frequent event, occurring in 20-50% of patients, mostly in the first postoperative year. Several retrospective studies have shown that predictors of IVR include clinical characteristics, surgical features and as well pathological characteristics (previous history of bladder cancer, pathological stage, lymph node involvement, cis, endoscopic distal ureter, etc.) management. Two prospective studies provide level I evidence for the safety and efficacy of intravesical single postoperative chemotherapy for patients treated with radical nephroureterectomy (RNU) for UTUC in order to prevent IVR...

Purpose Nephrolithiasis is an increasingly common ailment in the United States. Ureteroscopic management has supplanted shockwave lithotripsy as the most common treatment of upper tract stone disease. Ureteral stricture is a rare but serious complication of stone disease and its management. The impact of new technologies and more widespread ureteroscopic management on stricture rates is unknown. We describe our experience in managing strictures incurred following ureteroscopy for upper tract stone disease. Materials and methods Records for patients managed at 4 tertiary care centers between December 2006 and October 2015 with the diagnosis of ureteral stricture following ureteroscopy for upper tract stone disease were retrospectively reviewed...

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...

Miniaturization of ureteroscopy materials is intended to decrease tissue damage. However, tissue hypoxia and the gross and microscopic effects on tissue have not been adequately assessed. We compared the gross and microscopic effects of micro-ureteroscopy (m-URS) and conventional ureteroscopy (URS) on the urinary tract. We employed 14 pigs of the Large White race. URS was performed in one of the ureters with an 8/9.8 F ureteroscope, while a 4.85 F m-URS sheath was used in the contralateral ureter. Gross assessment of ureteral wall damage and ureteral orifice damage was performed...

Slit guidance ligand 2 (SLIT2) is a large, secreted protein which binds roundabout (ROBO) receptors on multiple cell types including neurons and kidney podocytes. SLIT2-ROBO2 mediated signaling regulates neuronal migration and ureteric bud (UB) outgrowth during kidney development as well as glomerular filtration in adult kidneys. Additionally, SLIT2 binds Gremlin, an antagonist of bone morphogenetic proteins (BMPs), and BMP-Gremlin signaling also regulates UB formation. However, direct crosstalk between the ROBO2-SLIT2 and BMP-Gremlin signaling pathways has not been established...
