OBJECTIVE: To evaluate oncologic outcomes of segmental ureterectomy (SU) compared with radical nephroureterectomy (RNU) for urothelial carcinoma of ureter. To evaluate whether tumor position is a factor to influence outcomes of different surgical procedures. METHODS: From November 2003 to June 2016, 131 patients with urothelial carcinoma of ureter underwent SU or RNU at our department. We used survival analysis and Cox regression models to compare oncologic outcomes after SU and RNU...

INTRODUCTION: Renal papillary necrosis is not commonly seen in daily practice, but can have severe consequences when it is not diagnosed in time. It is known to be associated with sickle cell hemoglobinopathies; however a wide range of etiologies are possible, and it is therefore not the first diagnosis clinicians consider in patients with sickle cell disease who present with hematuria. METHODS: A literature search was performed to summarize the current knowledge about renal papillary necrosis associated with sickle cell disease...

BACKGROUND: Extravesical Lich-Gregoir ureteroneocystostomy (UC) is the most widely used method for urinary reconstruction during kidney transplantation. Sometimes it is difficult to perform UC in cases with disused atrophic bladder. Pyelo-ureteral anastomosis (PUA) and uretero-ureteral anastomosis (UUA) may be preferred to UC for these patients. METHODS: We retrospectively reviewed the charts of 833 kidney transplant recipients operated on by our transplantation team between July 2010 and November 2014...

BACKGROUND: This case report describes a spontaneous tumor lysis syndrome due to a rare solid tumor. CASE PRESENTATION: A 65-year-old white woman had tumor lysis syndrome, which represent a dangerous oncological emergency. This syndrome occurs usually with a hematological tumor, but in this case our patient had a solid tumor, which was a rare extraskeletal osteosarcoma, localized in her pelvic region. She also had lung metastases and bilateral hydronephrosis. After spontaneous tumor lysis syndrome, she had acute renal insufficiency, which was treated with hemodialysis and successively with rasburicase, Kayexalate (sodium polystyrene sulfonate), and febuxostat...

Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common cause of chronic kidney disease in children. As CAKUT is a genetically heterogeneous disorder and most cases are genetically unexplained, we aimed to identify new CAKUT causing genes. Using whole-exome sequencing and trio-based de novo analysis, we identified a novel heterozygous de novo frameshift variant in the leukemia inhibitory factor receptor (LIFR) gene causing instability of the mRNA in a patient presenting with bilateral CAKUT and requiring kidney transplantation at one year of age...

Endometriosis can affect up to 10% of women of reproductive age, in a wide range of clinical presentations that vary from mild to severe or deep endometriosis. Deep endometriosis can affect the urinary tract in 1-5% to 15-25% cases. Even though deep endometriosis' surgeries are usually complex with higher rate of complications, conservative management is not always considered as an option because of its high failure rates. This paper describes two cases of deep endometriosis with ureteric involvement (hydronephrosis) treated conservatively with a double-pigtail stent plus a Levonorgestrel intrauterine device, after conservative surgery, who remained symptom free with no evidence of recurrence at 3 years follow-up, avoiding radical high-risk surgery...

Impacted stones frequently cause changes in the ureter, including edema of the ureteral wall, stone embedding in the ureteral mucosa or ureteral bending, which often preclude spontaneous passing of the stone and increase the risk of complications during surgery. When stone impaction is suspected preoperatively, management should be adapted accordingly. However, surgical treatment strategies remain controversial in pediatric patients because of the scarcity of cases reported. We describe the case of a 2-year-old girl with a right impacted ureteral stone who presented with gross hematuria and pyuria, but no metabolic risk factors or hematological abnormalities...

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a congenital visceral myopathy characterized by severe dilation of the urinary bladder and defective intestinal motility. The genetic basis of MMIHS has been ascribed to spontaneous and autosomal dominant mutations in actin gamma 2 (ACTG2), a smooth muscle contractile gene. However, evidence suggesting a recessive origin of the disease also exists. Using combined homozygosity mapping and whole exome sequencing, a genetically isolated family was found to carry a premature termination codon in Leiomodin1 (LMOD1), a gene preferentially expressed in vascular and visceral smooth muscle cells...

Over recent years routine ultrasound scanning has identified increasing numbers of neonates as having hydronephrosis and pelvi-ureteric junction obstruction (PUJO). This patient group presents a diagnostic and management challenge for paediatric nephrologists and urologists. In this review we consider the known molecular mechanisms underpinning PUJO and review the potential of utilising this information to develop novel therapeutics and diagnostic biomarkers to improve the care of children with this disorder...

Inguinal hernias involving the ureter, a retroperitoneal structure, is an uncommon phenomenon. It can occur with or without obstructive uropathy, the latter posing a trap for the unassuming general surgeon performing a routine inguinal hernia repair. Ureteral inguinal hernia should be included as a differential when a clinical inguinal hernia is diagnosed concurrently with unexplained hydronephrosis, renal failure or urinary tract infection particularly in a male. The present case describes a patient with a known ureteroinguinal hernia who proceeded to having a planned hernia repair and ureteric protection...
