Purpose: We identified risk factors for complications of the lower extremit
ies related to high lithotomy positioning during specific urethral reconstr
uction procedures in male patients.
Materials and Methods: Records from 185 open urethroplasties were evaluated
for position related complications of the lower extremities (the compartme
ntal syndrome, rhabdomyolysis, neurapraxia). Morphometric data (patient hei
ght, weight) and surgical details (duration of surgery and lithotomy positi
oning, types of repair and stirrups, stricture length and location) were as
sessed.
Results: In the 185 patients 18 position related complications (10%) were i
dentified, 4 of which were severe. Univariate analysis showed length of str
icture, and duration of surgery and lithotomy positioning to be statistical
ly significant risk factors (p <0.05). Height, weight, body mass index and
type of stirrups did not increase risk. Anterior end-to-end anastomosis and
straightforward buccal mucosa patch grafts entailed negligible risk. Longe
r procedures (prostatomembranous and penile skin flap repairs) had higher c
omplication rates (12% and 22%, respectively). Beginning penile skin flap p
rocedures with patients in the supine position during flap harvesting follo
wed by repositioning into high lithotomy for perineal flap transfer virtual
ly eliminated the risk of severe complications.
Conclusions: The risk of position related complications during urethral rec
onstruction is directly proportional to the duration of high lithotomy posi
tioning. Procedures of less than 5 hours in duration had minimal risk. For
complex flap procedures, we perform penile flap dissection with the patient
supine and reposition for perineal flap transfer.
