The kidneys are retroperitoneal organs applied to the posterior abdominal wall. Renal ectopia and structural alterations are of clinical significance. Most renal ectopia occurs in the pelvis and has a strong association with genitourinary pathologies. I the present study we report a rare case of bilateral pre-peritoneal pelvic renal ectopia with aberrant size, structure and renal vasculature. T...

The simultaneous occurrence of renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) in the same kidney is unusual. We report a 53-year-old man with ipsilateral synchronous renal adenocarcinoma and renal pelvic transitional cell carcinoma with severe hypercalcemia and a huge staghorn calculus in the opposite kidney. The patient was admitted to the hospital because of left flank pain an...

Carcinosarcoma is a malignant tumor of biphasic character consisting epithelial and mesenchymal components. This rarely-seen has an exceedingly aggressive nature. While it rare in the urinary system, appears even more rarely renal pelvis. Thus, there are few publications literature on carcinosarcomas originating from paper presents 42-year-old male patient with carcinosarcoma pelvis (CSRP), kid...

Vesicorenal reflux is a major side effect associated with ureteric stent placement. In a stented upper urinary tract when the bladder pressure rises, such as during bladder spasms (due to irritation caused by the stent) or voiding of the bladder, it drives urine reflux up the ureter, which, in turn, may be a contributory factor for infections in the renal pelvis. We develop a mathematical model...

Our previous studies have shown that the activation of the transient receptor potential vanilloid type 1 (TRPV1) expressed in the renal pelvis leads to an increase in ipsilateral afferent renal nerve activity (ARNA) and contralateral renal excretory function, but the molecular mechanisms of TRPV1 action are largely unknown. This study tests the hypothesis that activation of receptors of neuroki...
