TSUCHIDA, S., MORITA, T. and KONDO, S. A New in Vivo Method of Recording of the Electrical Activities of the Renal Pelvis. Tohoku J. exp. Med., 1982, 136 (2), 233-234 A new method is described which enables in vivo recording of electromyogram from the pelvicalyceal border (PC border) of the canine renal pelvis. At the PC border slow rising-potentials with constant intervals are recorded throughout the normo-uretic stage and the diuretic stage. The wave form of the discharge is very similar to that of the pacemaker potential obtained by the previous in vitro study. pelvic electromyogram; pacemaker of ureteral peristalsis; in vivo experiment

A new method for acquisition and analysis of single unit recording data
Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...

متن کاملSarcomatoid Carcinoma of Renal Pelvis Involving Ureter and Renal Parenchyma with Heterologous Osteosarcomatous Differentiation: A Case Report and Review of Literature
Sarcomatoid carcinoma is a high‑grade rare malignant tumor with both epithelial and mesenchymal components. Sarcomatoid carcinoma in the upper urinary tract is very rare. We reported here a case of sarcomatoid carcinoma of renal pelvis with osteosarcomatous differentiation, with involvement of the ureter and renal parenchyma in a 68-year-old female. Histologically, predominant pleomorphic spind...
متن کاملResults of Pyeloplasty in patients with Ureteropelvic Junction Obstruction in Pediatric Surgery Center in Bandar Abbas
Introduction: Ureteropelvic junction obstruction (UPJO) is associated with inadequate urine drainage from renal pelvis into ureter. UPJO results from incomplete recanalization of proximal ureter during fetal period which finally leads to hydrostatic distention of renal pelvis and calyces. Diagnosis is based on clinical symptoms, ultrasound, and diuretic isotopic renogram. Various surgical metho...
متن کاملNasopharyngeal Metastasis Originating From Beta-HCG Being Secreting From Transitional Cell Carcinoma of the Renal Pelvis: A Case Report
Introduction: Transitional cell carcinomas (TCC) of the upper urinary tract constitute only 7% of urothelial carcinomas. The majority of upper urinary tract TCC arises from the renal pelvis, followed by the ureter. The majority of the patients are presented with microscopic or macroscopic haematuria, flank pain, or symptoms due to metastasis; however, it can be asymptomatic in 10-15%. Case pre...
