BACKGROUND Renal cell carcinoma (RCCs) is the most common malignancy of the kidney. When RCC progresses, it is known to form tumor thrombus in the renal vein and/or inferior vena cava. However, RCC does not normally form tumor thrombus in the ureter or renal pelvis. CASE PRESENTATION A 43-year-old man presented to our department for the treatment of a renal tumor with asymptomatic gross hemat...

In a retrospective study of 185 patients with transitional cell carcinoma of the renal pelvis and ureter, of whom 127 were treated by total nephroureterectomy and 58 by conservative resection, the survival of those with superficial well differentiated tumours was greater than 90% in each group. When urothelium was left behind after conservative resection, there was a 22% rate of recurrence on t...

OBJECTIVE The aim of this study was to evaluate the relationship between urolithiasis and characteristics of renal shape in adult patients with horseshoe kidney (HSK) diagnosed on multidetector row computed tomography (MDCT). METHODS We evaluated 36 patients with HSK and urolithiasis (Group A) and 70 patients with HSK without urolithiasis (Group B) whose disease was diagnosed on non-contrast ...

Schwannomas are benign tumors that arise from the neural sheath of Schwann cells. Renal schwannomas are extremely rare and are commonly misdiagnosed as renal cell carcinoma, which typically results in a radical nephrectomy. We present a case of a renal schwannoma that mimics a renal pelvis tumor.

Introduction. Our objective is to report a case of an infrequent entity as the giant hydronephrosis. Case Report. We report the case of an 82-syear-old male referred for a poor general condition. A radiological study revealed a great left hydronephrosis secondary to an urothelial carcinoma. The patient died due to his poor general condition. A histological diagnosis revealed a transitional cell...

BACKGROUND Staghorn calculi are well-established risk factors for recurrent urinary tract infections (UTIs) and subsequent renal deterioration. Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and...

The widespread use of fetal ultrasonography results in a frequent antenatally observation of hydronephrosis, ureteropelvic junction obstruction (UPJO) accounting for the greatest fraction of congenital obstructive nephropathy. UPJO may be considered, in most cases, as a functional obstructive condition, depending on defective fetal smooth muscle/nerve development at this level, with lack of per...
