renal pelvis वाक्य

In "'pyeloscopy "', the endoscope is designed to reach all the way to the renal pelvis ( also called " pyelum " ), thereby allowing visualisation of the entire drainage system of the kidney.
The obstruction may be either partial or complete and can occur anywhere from the calyces of the renal pelvis . Hydronephrosis can also result from the reverse flow of urine from the bladder back into the kidneys.
GDNF, gonadal derived neurotrophic factor, is produced by the metanephric blastema and is essential in binding to the Ret receptor on the ureteric bud, which bifurcates and coalesces as a result to form the renal pelvis, major and minor calyces and collecting ducts.
