Effect of vesical feedback on rate of urine formation demonstrated by infusing hypotonic and hypertonic saline into the urinary bladder of dogs. Indian Journal of Physiology and Pharmacology. 1992 Jan; 36(1): 70-2http://imsear.searo.who.int/handle/123456789/107572The present study was undertaken to investigate the effect of the presence of solutions of different osmolality (hypertonic 3%, 4% and 5% hypotonic 0.1%, 0.2% and 0.3% in the urinary bladder on renal urine formation. The study was conducted on 36 dogs of either sex. 100 ml normal saline was used for distending the bladder. Various hypertonic and hypotonic solutions were infused inside the bladder and rate of urine formation was recorded. Presence of hypertonic fluid increased the rate of urine formation and hypotonic fluid decreased it.engAnimalsDogsFeedback --physiologyFemaleHypertonic SolutionsHypotonic SolutionsKidney --physiologyMaleOsmolar ConcentrationSodium Chloride --pharmacologyUrinary Bladder --physiologyUrodynamics --physiologyJournal Article
