of [greater than or equal to]150 ml was taken as a cutoff value for postpartum urinary retention (PPUR) as 92.3% of our study population had RU < 150 ml.
Another reason of urinary tract infection is residual urine
in patients with a diagnosis of urination disorder.
Due to non-availability of TRUS in our centre, only ultrasound abdomen for prostate size, consistency and residual urine
The dependent variable was the value of bladder outlet obstruction index >4o (urodynamic obstruction), while independent variables were: prostate volume, Qmax, mean voided volume, BOON, age, International Prostate Symptom Score and residual urine
. It was shown that the most significant variable determining obstruction was BOON (p=0.0006, OR=1.04), followed by Qmax (p=0.009, OR=0.9), with log likelihood 73.6, (p<0.0001).

Presence and volume of residual urine
was defined right after the urination act.

volume) and lower total PSA level on day 180 of the study.
decreased from 332 to 31 milliliters, and urinary-tract infections became negligible.
The residual urine
samples from routine pregnancy testing were evaluated for chlamydia, gonorrhea, and T.
In addition, non-oliguric patients typically had fewer complications by avoiding volume overload and subsequent pulmonary edema as some residual urine
Another possibility to explain the presence of a false negative in a single steer could be the interference of residual urine
produced before the development of metabolic acidosis increasing the urine pH thereafter.
After the 1st fractionation step, residual urine
was removed, and the procedure was repeated with a 2nd urine fraction (60 [micro]L maximum).
