OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

OBJECTIVE: Endometriosis is an estrogendependent disease. The incidence of urinary tract endometriosis (UE) increased during the last few years and, nowadays, it ranges from 0.3 to 12% of all women affected by the disease. The ureter is the second most common site affected. The ureteral endometriosis is classified in extrinsic and intrinsic. The aim of this study is to individuate the best treatments for each subset of ureteral endometriosis. MATERIALS AND METHODS: 32 patients diagnosed with surgically treated UE were retrospectively reviewed...

Ipsilateral inguinal herniation of the transplanted ureter has been reported as a rare cause of obstructive uropathy in renal transplant recipients. A 73-year-old man presented with acute renal failure 29 years after receiving a deceased donor renal transplant. Radiological investigations demonstrated marked hydronephrosis of the left iliac fossa transplant kidney and herniation of the distal transplant ureter and bladder into the right inguinal canal. The patient underwent placement of a nephrostomy and antegrade stent followed by definitive hernia repair with return of graft function to baseline level...

T-box (Tbx) genes encode an ancient group of transcription factors that play important roles in patterning, specification, proliferation, and differentiation programs in vertebrate organogenesis. This is testified by severe organ malformation syndromes in mice homozygous for engineered null alleles of specific T-box genes and by the large number of human inherited organ-specific diseases that have been linked to mutations in these genes. One of the organ systems that has not been associated with loss of specific T-box gene function in human disease for long is the excretory system...

Inbred MRL/MpJ mice show several unique phenotypes in tissue regeneration processes and the urogenital and immune systems. Clarifying the genetic and molecular bases of these phenotypes requires the analysis of their genetic susceptibility locus. Herein, hydronephrosis development was incidentally observed in MRL/MpJ-derived chromosome 11 (D11Mit21-212)-carrying C57BL/6N-based congenic mice, which developed bilateral or unilateral hydronephrosis in both males and females with 23.5% and 12.5% prevalence, respectively...

A 1-year-old male infant presented with fever and abdominal lump for 3 months with increased leucocyte count (15 300/mm(3)) and serum creatinine (0.83 mg%). Abdominal ultrasound and renal scan demonstrated solitary left kidney with dilated tortuous left ureter. Voiding cystourethrogram was unequivocal. Left percutaneous nephrostomy was placed after poor response to perurethral catheterisation. His serum creatinine dropped to 0.58 mg/dL. Subsequent percutaneous nephrostogram and CT nephrostogram showed dilated left pelvicalyceal system, dilated, tortuous left ureter...

INTRODUCTION: The presence of concomitant vesicoureteric reflux (VUR) and ureteropelvic junction obstruction (UPJO) is uncommon. Nevertheless, the reported VUR coexisting with asymptomatic unilateral isolated hydronephrosis (AUIH) requiring pyeloplasty for correction of UPJO was of low grade and mostly resolved during conservative follow-up. Therefore, VCUG may be not indicated in these children except if voiding symptoms, urinary tract infection (UTI), dilated ureters, or bladder and ureteric abnormalities are suspected...

INTRODUCTION: Liposarcomas represent 20-30% of adult soft tissue tumors and its abdominal localization occurs only in 5% of cases. Most are asymptomatic, but few present with abdominal mass and pain, fatigue, nausea, vomiting. They infiltrate adjacent organs and cause intestinal obstruction, intestinal ischemia-perforation, hydronephrosis, ureteric fistula and even aortic rupture. Here we aimed to report a rare case of a giant liposarcoma which originated from mesentery. PRESENTATION OF CASE: A 45-year-old male presented with slightly abdomen distention, urinary retention, oliguria since fifteen days...

We present an extremely rare case of ureteric obstruction caused by a migrated intrauterine device. A 36-year-old female with complaints of almost 10 months left flank pain presented to our hospital. She used an IUD for contraception for 6 months after the birth of her first child. The IUD was not visible then. Ultrasonography (US) revealed that left severe hydronephrosis and upper ureterectasis. Pelvic computed tomography (CT) found that IUD was located very close to the lower ureter which was adjacent to the third anatomize physiological narrow...

BACKGROUND: The classical theory of Müllerian origin of upper vagina fails to explain complex urogenital malformations like OHVIRA syndrome; the Acien's hypothesis, however, unravels the hidden embryopathogenesis. As per Acien, Wolffian (mesonephric) ducts instead of Müllerian ducts and sinovaginal bulbs, give rise to the vagina. The new hypothesis, however, retains the concept of origin of the ureters (with ureters inducing renal development) by the former and the uterus by Müllerian ducts...

Renal interstitial fibrosis is an inevitable consequence of virtually every type of chronic kidney disease. The underlying mechanisms, however, are not completely understood. In the present study, we identified surfactant protein A (SP-A) as a novel protein factor involved in the renal fibrosis induced by unilateral ureter obstruction (UUO). UUO induced SP-A expression in mouse kidney epithelium, likely due to the increased acidic stress and inflammation. Interestingly, SP-A deficiency aggravated UUO-prompted kidney structural damage, macrophage accumulation, and tubulointerstitial fibrosis...

BACKGROUND: Standard treatment of advanced cervicovaginal cancer [international federation of gynecology and obstetrics (FIGO) stages II(B), III(A, B), IVA] is (chemo-)radiation excluding the possibility of systematic histopathological assessment of locoregional tumour spread. Laterally extended endopelvic resection (LEER) and therapeutic lymph node dissection (tLND) are novel surgical treatment options for advanced cervicovaginal cancer. METHODS: The therapeutic efficacy of LEER for locally advanced primary and recurrent cervicovaginal cancer was reassessed by an update of the prospective observational trial at the University of Leipzig...

A 77-year-old man with urinary tuberculosis developed post renal anuria two days after starting an anti-tuberculosis drug regimen. He had bilateral hydronephrosis, and his right kidney was radiologically diagnosed to be non-functioning. A transurethral catheter was placed in the left ureter. No improvement in the ureteral stricture was noted during the initial three weeks of treatment; however, the stricture did thereafter improve after the commencement of oral prednisolone. In cases of urinary tuberculosis, ureteral stricture can deteriorate and result in ureteral obstruction during anti-tuberculosis treatment...

The CyberKnife is a robotic stereotactic body radiotherapy (SBRT) system which has shown promising results for many malignances with good efficacy and low toxicity. This study aims to evaluate the response and local control (LC) obtained with CyberKnife in the management of iliac lymph node metastases (ILNM). Twenty-two patients with 27 ILNM were treated by CyberKnife from May 2010 to May 2016. Median follow-up time was 33 months (8-97). The complete response, partial response, stable disease and progression disease rates were 37...

INTRODUCTION: Laparoscopic reconstructive surgery is associated with a steep learning curve related to the use of two-dimensional (2D) vision and rigid instruments. With the advent of robotic surgery, three-dimensional (3D) vision, and articulated instruments, this learning curve has been facilitated. We present a hybrid alternative to robotic surgery, using laparoscopy with 3D vision and articulated shears. OBJECTIVE: To compare outcomes of children undergoing pyeloplasty using 3D laparoscopy with articulated instruments with those undergoing the same surgery using standard laparoscopy with 2D vision and rigid instruments...

WAGR syndrome is caused by an 11p13 deletion and includes Wilms' tumor, aniridia, genitourinary anomalies and mental retardation. We encountered a case of a dysgerminoma originating in an ectopic ovary in a woman with WAGR syndrome. Our patient was a 24-year-old nulliparous woman who was diagnosed with WAGR syndrome. The patient had undergone left nephrectomy for a Wilms' tumor and postoperative chemotherapy at the age of 7 months. She also had a history of glaucoma surgery in both eyes, and was followed up at the Department of Pediatrics for diabetes mellitus, hypertension, liver dysfunction and hyperuricemia...

Background: Fibroepithelial polyps (FEPs) are a rare cause of ureteropelvic junction (UPJ) obstruction. Radiologists and urologists are not always confident with this disease because of its rarity, complex diagnosis, and heterogeneity of the available treatment options. Case Presentation: We present the endourologic diagnosis and the robotic management of a ureteral polyp close to the left UPJ. A 16-year-old woman with a 12 years history of left lumbar pain was referred to our Center. A computed tomography scan detected a left hydronephrosis with no signs of obstructions at MAG-3 scintigraphy...
