Abstract:
A serious voiding disorder or urinary incontinence represent indications for long-term catheterization of the urinary bladder. Treatment by a transurethral or suprapubic bladder catheter for life-long bladder drainage is accompanied by technical short-term complications and long-term sequelae. The mortality risk associated with inserting a suprapubic catheter is approximately 2% due to an incorrect bladder puncture. Long-term consequences of life-long bladder drainage are hematuria, infection, spasms, stone formation, obstruction, catheter loss, risk of falls and automanipulation especially in cognitively impaired persons. These constitute frequent reasons for emergency treatment or hospitalization. Further problem areas are dependency on caregivers to perform the catheter change and dermal problems in the area of the fistula stoma. To what extent this limits the quality of life of those affected remains unclear up to now. The acute complications and the long-term consequences of life-long bladder drainage make careful decision-making necessary after other therapeutic options have failed, are not appropriate or not desired.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
