The renal pelvis: machinery that concentrates urine in the papilla.
نویسندگان
چکیده
Two decades ago, Bodil Schmidt-Nielsen and Bruce Graves documented the rhythmic contractions of the renal pelvis in a remarkable video, visually demonstrating how peristaltic waves empty the papilla and how the subsequent elastic recoil draws water from the collecting duct and into the tethered-open ascending vasa recta. Thus a periodic hydrostatic gradient generates an axial osmotic gradient. This review recapitulates the video and offers a link to figures and scenes digitized from the original tape.

On the function of the mammalian renal papilla and the peristalsis of the surrounding pelvis
This is an informal personal review of the development over time of my ideas about the concentrating mechanism of the mammalian renal papilla. It had been observed that animals with a need to produce a concentrated urine have a long renal papilla. I saw the function of the long papilla in desert rodents as an elongation of the counter-current concentrating mechanism of the inner medulla. This m...
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 کاملAngiotensin induces the urinary peristaltic machinery during the perinatal period.
The embryonic development of mammalian kidneys is completed during the perinatal period with a dramatic increase in urine production, as the burden of eliminating nitrogenous metabolic waste shifts from the placenta to the kidney. This urine is normally removed by peristaltic contraction of the renal pelvis, a smooth muscle structure unique to placental mammals. Mutant mice completely lacking a...
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...
