Hematuria during labour in previous LSCS is sign 
Select and explain. 
A. Impending rupture of scar, B. Urethral trauma, C. Prolong labour, D. Sepsis
A: Impending rupture of scar
Answer: A: Impending rupture of scar 
Explanation: Now friends - here in the question it is asked specifically that hematuria is seen in a patient with previous LSCS during
labour - which indicates impending rupture of scar.
"There are no reliable signs of impending uterine rupture that occurs before labor, although the sudden appearance of gross hematuria is suggestive.”
COGDT 10/e, p 340
Here in this questions obstructed labor is not given in the options, but even if it was given, I would have still opted for impending scar rupture as the question is specifically asking, in a case of previous LSCS.
