BACKGROUND IgG4-related disease is a recently recognized systemic disease characterized by storiform fibrosis with infiltration of IgG4-positive plasma cells. In rare incidences, IgG4-related renal disease can present as a solitary mass lesion at renal pelvis and can pose a diagnostic challenge since these lesions mimic malignancy. Herein, we present a rare case of IgG4-related disease presenti...

INTRODUCTION Autosomal dominant polycystic kidney disease (ADPKD) is a multisystem hereditary disease characterized by formation of cysts in the ductal organs. Renal pelvis malignancy in ADPKD is very rare and sporadically reported in the previous literature. Here, we report the first case of renal pelvis squamous cell carcinoma with tumor embolus in a 35-year-old ADPKD patient. The patient pre...

A 5 day old baby, with known left hydronephrosis which discovered by prenatal US presented with gastrointestinal tract obstruction. Laboratory work up demonstrated abnormal renal function and metabolic acidosis combined with hyperkalemia. Radiology tests showed bilateral hydronephrosis with huge left renal pelvis crossing the midline and causing deviation of the gut laterally. This acute presen...

Background Fetal hydronephrosis is a common urinary tract anomaly that may result in renal parenchyma damage. Ultrasound is considered a simple, noninvasive procedure to diagnose and track antenatal hydronephrosis. Our aim was to study the clinical course of fetal hydronephrosis in fetuses. Materials and Methods</...

We herein report a case of a renal pelvic tumor that developed in the residual left renal pelvis after right nephroureterectomy, left ureterectomy and total cystectomy in a patient with multiple urothelial tumors. The tumor was endoscopically ablated through a nephrostomy tract, and mitomycin C irrigation was carried out. We designed a novel constant-pressure irrigation system for effective and...

Nephrolithiasis is a common entity encountered in general population. Nephrolithiasis refers to formation and impaction of stones in renal pelvis and calyces. Long standing stones cause irritation, chronic inflammation and may cause ‘metaplasia’ of lining epithelium. The metaplasia is commonly of squamous and glandular epithelium. Metaplastic epithelium may further undergo dysplasia and result ...

Carcinosarcoma is a rare type of renal pelvis malignancy, the diagnosis of which requires the presence of malignant epithelial and mesenchymal components. The prognosis of this disease is extremely poor due to its rapid progression and widespread metastases. The present study describes a case of carcinosarcoma involving the right renal pelvis in a 73-year-old female who presented with intermitt...
