Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as: incontinence [1] frequent urination; sudden, strong urges to urinate but nothing comes out
In this test, first published in 1997, a software-steered inflatable cuff (similar as in a blood pressure meter) is placed around the penis to measure the pressure of urinary flow. [28] By applying this methode, a study of 2013 showed that 94% of the patients with the pre-surgery test result "Obstruction" had a successful surgery outcome.
A uroflometer for measuring urine flow. Urine flow rate or urinary flow rate is the volumetric flow rate of urine during urination. It is a measure of the quantity of urine excreted in a specified period of time (per second or per minute). It is measured with uroflowmetry, a type of flow measurement.
A triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. The outcome is considered excellent for 80–90% of BPH patients. The procedure carries minimal risk for erectile dysfunction, moderate risk for bleeding, and a large risk for retrograde ejaculation. [2]
Following the procedure, the prostatic tissue will be swollen and irritated. Urologists often place a Foley catheter to prevent the patient from having urinary retention. After three to five days the Foley catheter can be replaced by a temporary prostatic stent to improve voiding without exacerbating irritation symptoms.
Cystometry, also known as flow cystometry, is a clinical diagnostic procedure used to evaluate bladder function. Specifically, it measures contractile force of the bladder when voiding . The resulting chart generated from cystometric analysis is known as a cystometrogram (CMG), which plots intravesical pressure against the volume of fluid in ...
At shorter periods of follow-up (2–4 years) the satisfaction rates achieved over 90%. [29] [32] [4] In another study with mean follow-up of over 7 years, the overall satisfaction rate measured 3.9 on a scale from 0 to 5. [32] The satisfaction rate in patients after radiotherapy does not seem to be unfavorably affected. [34]
Transurethral incision of the prostate-—one or two small cuts in the prostate gland—can improve urine flow and correct other problems related to an enlarged prostate. [ citation needed ] Indications
