We performed construction of continent urinary reservoir in an 8-year-old girl with cloacal exstrophy who had double stoma of ileostomy and colon conduit. Preoperative evaluation revealed non-functioning right kidney with severely dilated renal pelvis and calyxes in her pelvis. Urinary reservoir was constructed using detubularized colon segment which had been used as the urinary conduit and dil...
Spontaneous renal pelvis rupture is a rare situation. It is nearly always related to underlying renal abnormalities caused by calculus, infection, tumor or pregnancy, resulting in hydronephrosis. In some situations, it is iatrogenic, such as fluid overload during diagnostic or therapeutic interventions. Here, we present a case of spontaneous renal pelvis rupture with no predisposing factor foun...
Primary squamous cell carcinoma (SCC) of the renal pelvis is a very rare tumor often associated with renal calculi and chronic infections. There are only a few articles in literature which report renal pelvis SCC in kidneys treated for renal tuberculosis, diagnosed after nephrectomy. We report the case of SCC in a hydronephrotic kidney previously treated for tuberculosis, diagnosed by ultrasoun...
Metastasis-associated in colon cancer 1 (MACC1) has recently been identified as a novel independent prognostic indicator for metastasis occurrence, overall survival and cancer-free survival for patients with colon cancer and other solid tumors. In this study, we investigated the role of MACC1 in the development and progression of renal pelvis carcinoma, a form of upper tract urothelial carcinom...
We aimed, in this study, to determine the distribution of α-1 AR subtypes in rat and human pelvis and calyces, and to evaluate, by comparing these two species, the possibility of rats to be used as models for humans. Twenty patients with renal carcinoma were included into the study. The patients underwent radical nephrectomy for renal cell carcinoma (RCC). After nephrectomy, specimens were eval...
The presence of NADPH oxidase (Nox) in the kidney, especially Nox4, results in H2O2 production, which regulates Na(+) excretion and urine formation. Redox-sensitive transient receptor potential vanilloid 1 channels (TRPV1s) are distributed in mechanosensory fibers of the renal pelvis and monitor changes in intrapelvic pressure (IPP) during urine formation. The present study tested whether H2O2 ...
Urothelial carcinoma (UC) of the renal pelvis has been rarely shown to metastasize to the skin. Tumor seeding from iatrogenic procedures is a source of spreading of UC to the skin. We herein present a case of primary UC of the renal pelvis with spreading to the skin from a percutaneous nephrostomy tract.
Stimulation of capsaicin receptors results in an increase in afferent renal nerve activity (ARNA), but it is unclear how capsaicin contributes to sensory activation intrarenally. Here, we studied the relationships between capsaicin receptor activation, substance P (SP) release, and the sensory response in the rat renal pelvis. Immunoblots showed that one of the capsaicin receptors, transient re...
BACKGROUND IgG4-related kidney disease is a comprehensive term for renal lesions associated with IgG4-related disease, which mainly manifests as plasma cell-rich tubulointerstitial nephritis with increased IgG4+ plasma cells and fibrosis. IgG4-related kidney disease in the renal pelvis is rare. CASE PRESENTATION We describe a 53-year-old Asian woman who was referred to our hospital with a spa...
Squamous cell carcinoma (SCC) of the renal pelvis is an aggressive tumor with insidious onset of unspecific symptoms and advanced stages at diagnosis. It is a rare entity, accounting for 0.5-8% of renal tumors. In this paper, we describe the case of a patient with a history of recurrent nephrolithiasis that presented with an aggressive form of SCC of the renal pelvis with rapid relapse after re...
