Effect of long-term chemical sympathectomy on function of canine urinary tract

Destruction of the adrenergic terminals in the ureter, bladder, and urethra was produced and maintained in 4 dogs for periods up to twelve months by biweekly intraperitoneal injections of 6-hydroxydopamine. The effects on urine transport, storage, and elimination were studied. The results are discussed in the light of current knowledge regarding the sympathetic innervation of these organs and its function.
