Primary renal synovial sarcoma(PRSS) is a rare entity. It should be considered as one of the differential diagnoses of spindle cell tumors of the kidney. Immunohistochemistry and genetic translocation studies should be used to confirm the diagnosis. Due to lack of consistent literature data regarding the treatment options, it remains a therapeutic challenge. In view of chemosensitive nature of the tumor, we propose multimodality treatment in form of surgery and chemotherapy in these patients. Here we report a rare case of PRSS in a 17 year old female...

OBJECTIVE: To assess outcomes of ureteroscopy for treatment of stone disease in the elderly. Ureteroscopy (URS) is an increasingly popular treatment modality for urolithiasis and its applications are ever expanding with the development of newer technologies. Its feasibility and outcomes within the elderly population to our knowledge remain under-reported. MATERIALS AND METHODS: We examined the patient demographics and surgical outcomes from our prospective database for patients ≥70 years who underwent URS for urolithiasis, in a 5-year period between March 2012 and December 2016...

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...

Ureterocalicostomy is usually a salvage procedure for recurrent pelvi-ureteric junction (PUJ) stricture or upper ureteric injury. It requires meticulous dissection of the upper ureter, and lower pole nephrectomy is considered an essential step to achieve a wide funneled and dependent ureterocaliceal anastomosis. We, hereby, highlight the importance of guillotine lower pole nephrectomy through a case report of recurrent PUJ stricture managed with ureterocalicostomy that failed due to the omission of lower pole nephrectomy...

INTRODUCTION: Congenital pelviureteric junction obstruction (PUJO) is one of the most frequent causes of neonatal hydronephrosis. Obstruction at the PUJ has potential severe adverse outcomes, such as renal damage. While pyeloplasty has been established as the definitive treatment, the exact pathophysiology of congenital PUJO remains unknown. Recent research has proposed neuronal innervation defects as an etiological factor in congenital PUJO. We aim to study the expression of various neuronal markers in PUJO specimens compared with controls, and evaluate whether severity of renal disease or dysfunction pre-operatively is related to expression of neuronal markers in resected PUJO specimens...

PURPOSE: We compared the outcomes in patients who were <1 year old and had hydronephrosis with SFU grade 3-4 PUJ obstruction to observe the potential recovery of renal morphology and DRF after successful pyeloplasty. METHODS: All children younger than 1 year old with SFU grade 3-4 PUJ obstruction from January 2013 to June 2015 were retrospectively analyzed. A total of 92 children were grouped according to their DRF value at pyeloplasty as follows: DRF from 30 to ≤35% (group I) and DRF from 35 to ≤40% (group II)...

OBJECTIVE: To report our experience on gas endoscopy as the first step of pelvi-ureteric junction (PUJ) obstruction repair when complicated by nephrolithiasis. MATERIALS AND METHODS: Stone formation because of urine stasis is a known complication of PUJ obstruction and an indication for its surgical repair. The undisputed results of the Anderson-Hynes dismembered pyeloplasty make it a quasi-gold standard; however, the identification and extraction of calyceal stones through the laparoscopic route can be challenging...

In the context of ante-natally diagnosed hydronephrosis, the vast majority of children with a dilated renal pelvis do not need any surgical treatment, as the dilatation resolves spontaneously with time. Slow drainage demonstrated at Tc-99m-mercaptoacetyltriglycine (MAG3) renography does not necessarily mean obstruction. Obstruction is defined as resistance to urinary outflow with urinary stasis at the level of the pelvic-ureteric junction (PUJ) which, if left untreated, will damage the kidney. Unfortunately this definition is retrospective and not clinically helpful...

PURPOSE: The aim of this study is to analyze results of retrograde endopyelotomy with cutting balloon for treatment of ureteropelvic junction obstruction (UPJO) in infants. METHODS: We routinely treat patients with UPJO under 18 months of age with retrograde high-pressure balloon dilatation of the pelviureteric junction (PUJ). During the procedure, in these cases where narrowing at the PUJ persists, endopyelotomy with cutting balloon is performed. Endopyelotomy is performed over guidewire with 5-mm Cutting Balloon™ under fluoroscopic control...

Ureterocalycostomy can be performed in patients in whom desired methods of treating secondary PUJ (Pelvi-Ureteric Junction) obstructions either failed or could not be used. In our study, one child and two adults in whom one redo-ureterocalycostomy and two ureterocalycostomies were performed for severely scarred PUJ. The causes for secondary PUJ obstruction were post-pyelolithotomy in one case, post-pyeloplasty and ureterocalycostomy for PUJ obstruction in the second patient and the third patient had long upper ureteric stricture post-ureteropyeloplasty due to tuberculosis...

PURPOSE: Laparoscopic transposition of lower-pole crossing vessels (LPCV) has been described as an effective alternative to dismembered pyeloplasty in selected indications of hydronephrosis, with purely extrinsic vascular PUJ obstruction. We hypothesized that the initial good results of laparoscopic transposition of LPCV in children presenting with pure extrinsic PUJO were sustained at puberty when these children go through statural growth, without inducing significant changes in systemic arterial blood pressure...

Anomalous kidneys are mostly asymptomatic and are often found incidentally during physical or radiological investigations for urological or other medical complaints. The associated genital anomalies ranges from 15% to 45%. Females are associated with bicornuate or unicornuate uterus, rudimentary or absent uterus while males have undescended testes, duplication of the urethra, and hypospadias. A 21 year old married female presented with on and off lower abdomen pain for the past one year with history of primary amenorrhea...

AIM: To assess if calibration of the ureteropelvic junction (UPJ) using a high-pressure balloon inflated at the UPJ level in patients with suspected crossing vessels (CV) could differentiate between intrinsic and extrinsic stenosis prior to laparoscopic vascular hitch (VH). MATERIALS AND METHODS: We reviewed patients with UPJO diagnosed at childhood or adolescence without previous evidence of antenatal or infant hydronephrosis (10 patients). By cystoscopy, a high-pressure balloon is sited at the UPJ and the balloon inflated to 8-12 atm under radiological screening...

BACKGROUND/AIM: The controversy over the postnatal management of infants with antenataly detected hydronephrosis (ANH) still exists. We presented the results of diuretic 99mTc diethylenetriamine pentaacetic acid (DTPA) renography in 30 infants with the antenatal diagnosis of unilateral renal pelvic dilatation. The aim of this study was to assess the renal function determined by the pattern of drainage and split renal function (SRF) on diuretic renography and to correlate these findings with anteroposterior pelvic diameter (APD) estimated by ultrasonography...

Many centres favour endourological management over shock wave lithotripsy (SWL) in the management of moderate-sized (10-20 mm) renal stones. International guidelines support all available modalities for the treatment of these stones. The aim of this study was to evaluate the efficacy of SWL in the treatment of 10- to 20-mm renal stones. From January 2013 to October 2014, all patients with a renal stone measuring between 10 and 20 mm in maximum diameter on CT scan that were eligible for lithotripsy were included...

UNLABELLED: Diuretic nephrogram is important diagnostic tool in the postnatal follow-up of asymptomatic antenatally detected hydronephrosis (HN). In the last decades, two quantitative indices of renal excretion, output efficiency and the residual kidney counts normalized to the 1-2min counts (normalized residual activity, NORA) have been proposed, that enhance the accuracy of technique to detect kidneys with obstruction. Unfortunately, in many nuclear medicine departments in developing countries the obsolete computer systems do not give the opportunity of sophisticated analysis of nephrogram...
