Urodynamic profile of lower urinary tract symptoms in young men: A testimony of the truth?

Aim: To evaluate the impact of urodynamic study (UDS) in the management of young men presenting with lower urinary tract symptoms (LUTSs).

Materials And Methods: This is a retrospective, observational study of urodynamic findings of 128 patients presented with LUTS at the Department of Urology, Institute of Nephrourology, Bangalore, over a period of 5 years (August 2014 to July 2019). Pre- and post-UDS diagnoses as well as treatment modalities were compared to evaluate the usefulness of UDS.

Urodynamic profile in posterior urethral valve patients following fulguration: Does age at fulguration matter?

Introduction: Children with posterior urethral valve (PUV) may develop urinary bladder (UB) dysfunction even after valve fulguration (VF). Using Urodynamics (UDS), we sought to identify whether age at VF and time elapsed since VF contributed to UB dysfunction.

Materials And Methods: Between January 2009 and July 2016, 39 PUV patients referred to a tertiary care center for UDS were classified into Groups A and B (based on age if <2 or ≥2 years at VF) and subclassified into Group A1/A2 and B1/B2 depending on time duration after VF (TVU).

Nasogastric tube as abdominal pressure sensor in urodynamics-Proof of concept of a novel approach.

Aims: The standard sensor for abdominal pressure (Pabd) measurement in urodynamics (UD) is a rectal sensor. In patients where the rectum is not available due to prior surgery or when external anal sphincter (EAS) tone is poor, rectal sensor may slip, making Pabd recording unreliable. Vaginal Pabd measurement and wireless vaginal sensors have been tried.

A quantitative comparison between free uroflow variables and urodynamic data, and the effect of the size of urodynamic catheters on its interpretation.

Objective: To assess the effect of the urodynamic catheter on the urinary flow rate and residual volume in various urodynamic diagnoses, and compare the outcome when using a smaller catheter, as the effect of this catheter on free uroflow variables is mostly studied in patients with bladder outlet obstruction (BOO) and little is known about its effect in other urodynamic diagnoses.

Patients And Methods: In all, 319 men undergoing a pressure-flow study (PFS) with a 5 F filling and 5 F measuring bladder catheter were subdivided into three groups based on a urodynamic diagnosis, i.e.
