Study summary

The goal of this study is to learn whether the change or patient position might effect the results of invasive urodynamic study in males.

Read the detailed description

Males will be randomised as Group 1 and Group 2. In Group 1, invasive urodynamic study will be performed first in sitting then repeated in standing position. In Group 2, invasive urodynamic study will be performed first in standing then repeated in sitting position. Results will be compared.

Interventions

  • Diagnostic testInvasive Urodynamic Study

    Invasive Urodynamic Study (Filling cystometry and pressure-flow study) Under sterile conditions and at lithotomy position, an urethral and a rectal catheter will be inserted. Bladder will be filled by sterile saline slowly. The first feeling of urine, the first sensation of urination and the sensation of severe desire to urinate will be recorded step by step. Vesical, rectal and detrusor pressures will be monitorized during these period. After the strong desire to void sensation, filling cystometry phase will be completed. Sterile saline infusion is stopped. While the patient urinates the vesical, detrusor and rectal pressures, the maximum and average urine flow rates will be recorded.
