  • Title: The effects of double J stents on renal pelvic dynamics in the pig.
    Author: Payne SR, Ramsay JW.
    Journal: J Urol; 1988 Sep; 140(3):637-41. PubMed ID: 3411694.
    Abstract:
    Intra-pelvic pressure and peristaltic activity were measured before and during diuresis in 26 minipigs, immediately, one week and three weeks following ureteric intubation with 5 and 6F polyethylene double J stents. Changes in these dynamic parameters were seen which indicate that these stents caused renal outflow obstruction. The severity of this obstruction appears dependent upon the size of the catheter and the temporal length of intubation. This study indicates that double J stents provide sub-optimal drainage of the renal pelvis and damaged ureter.
