Rationalization of interpretation of uroflowmetry for a non‐caucasian (Indian) population: conceptual development and validation of volume‐normalized flow rate index

Abstract

Volume-normalized flow-rate index with BV as denominator (Q/BV(2)) is has highly discriminative value in screening for voiding dysfunction. Population-specific Q-BV nomograms are more specific and predictive than Caucasian Q-VV nomograms.

Can the idealized voider derived flow indexes be a measure of voiding efficiency and how accurate are they?

“…Our most recent publication where we have developed an idealized voider flow equation (IVFE) to calculate Qmax and Qavg and then converting the Actual Q/Estimated Q into a flow index, normalizes for the total bladder volume at the time of the void and thereby corrects for the aforementioned flaw in uroflowmetry interpretation. In the adult literature a study using a flow index based on total bladder volume substantiates our premise that formulas based off total bladder volume are a better method to separate out dysfunctional voiders …”

Gabapentenoids in pain management in urological chronic pelvic pain syndrome: Gabapentin or pregabalin?

“…Search criteria—the hospital database for urology department (hospital management system) was searched for ICD‐9 codes 729.2 (neuralgia, neuritis, radiculitis, unspecified), 719.45 (pain in joint, pelvic region, and thigh), 338.29 (other chronic pain), 601.9 (prostatitis, unspecified), 601.1 (chronic prostatitis), 601.8 (other inflammatory disorders of prostate), and 608.0 (seminal vesiculitis). The medical record files of all patients having at least one of these codes were reviewed and after confirming inclusion the following data were collected and tabulated: Patient demographics and comorbidities. Symptoms—duration of symptoms. Location and degree of pain (using visual analog score 0‐10) at each visit. Clinical examination—specifically genital and digital rectal. Semen culture, expressed prostatic secretion (EPS) culture. Post EPS or post ejaculation urine routine and culture. Uroflowmetry, ultrasonography of prostate. Antibiotics—dose and duration; criteria for antibiotics were either a positive semen culture or tender prostate or both. Such patients were included only if pain persisted after completion of antibiotic course (i.e., from category II to III). Alpha blockers—dose and duration. Neuromodulators (pregabalin, gabapentin, amitriptyline) dose, duration, and side effects. Other treatment. …”

Male bladder outlet obstruction: Time to re‐evaluate the definition and reconsider our diagnostic pathway? ICI‐RS 2015

“…Several nomograms have been proposed for indicating if the flow measured represents abnormal voiding. [25][26][27][28][29] There are, however, significant differences between these nomograms, not just in the points of cut off chosen, but also in the variables used. For instances, the Siroky nomogram uses bladder volume on the horizontal axis, whereas the Liverpool nomogram uses voided volume.…”
