Pelvic laparotomy without an indwelling catheter. A retrospective review of 949 cases.

A retrospective review of 949 cases of pelvic laparotomy without an indwelling catheter was conducted. Contrary to traditional beliefs, this study found that the use of an indwelling catheter was not necessary to assure either adequate exposure during operation or satisfactory voiding in the postoperative period. Various prophylactic steps included staff attention to the preoperative and postoperative voiding needs of patients and occasional bladder needling during operation. These efforts resulted in a low (22.1%) postoperative distress catheterization rate with no complications if needling was done. Urinary infection rates ranged from less than 1% for patients who did not require distress catheterization to 3.9% for a comparative population of patients who had an indwelling catheter during and after operation. Abstaining from the use of an indwelling catheter was also associated with lower cost and greater patient satisfaction.

Immunohistochemical localization of fibronectin in human and rat uterine cervices.

Paraffin sections of 95% ethanol-fixed uterine cervices from adult, cycling rats and from human patients undergoing elective hysterectomy were immunostained by the peroxidase-antiperoxidase technique after exposure to antisera against fibronectin. Light microscopic study of uterine cervical stroma from both species showed an irregular distribution of fibronectin between compactly arranged collagenous fibers and a more uniform deposition around scattered bundles of smooth muscle fibers. In loosely arranged areas of stromal collagen, fibronectin was found in a filamentous, occasionally punctate, distribution. There was moderate to heavy staining with immunoperoxidase for fibronectin in the regions of the basement membrane underlying cervical epithelia and in the connective tissue stroma immediately subjacent to the basement membrane. Fibronectin was also present in the walls of most blood vessels and in the connective tissue investments of peripheral nerve fascicles. These findings suggest that fibronectin may be another component of extracellular matrix in the uterine cervical wall of non-gravid human subjects and rats in addition to collagen and glycosaminoglycans.
