Feasibility Study of Photovaporisation of Prostate With a Limitated Length of Catheterization of 3 Hours

Not Applicable

Completed

• Conditions: Benign Prostatic Hypertrophy
• Interventions: Other: Catheter

• Registration Number: NCT02401581
• Lead Sponsor: Centre Hospitalier Universitaire de Nice

Brief Summary

Benign hypertrophy of the prostate (BPH) is the most frequent pathology in the urinary tract of middle-aged men. In recent years, to enable BPH treatment with larger volumes and to reduce the risk of hemorrhage known to be associated to the transurethral resection of prostate treatment, transurethral photovaporisation of the prostate (PVP ) with the GreenLight (GL) XPS 180 W was developed. Therefore, the question arises to maximally reduce the length of catheterization to facilitate outpatient surgical management of prostate adenoma.

In the investigators study, the investigators propose to evaluate the failure rate of an early removal of the catheter 3 hours post-operative after a PVP procedure with GL 180 W/XPS in selected patients on general anesthesia or spinal anesthesia. To this end, the investigators realize a national multicenter prospective study including 300 patients. The effectiveness of this model of management is defined by absence of a need for re-catheterization in the post -operative period of 24 hours.

Arm && Interventions

Group	Intervention	Description
rate of early removal of the catheter	Catheter	In our study, we propose to evaluate the failure rate of an early removal of the catheter 3 hours post-operative after a PVP procedure with GL 180 W/XPS in selected patients on general anesthesia or spinal anesthesia for limiting autonomic effects on the bladder and ensure fastest possible recovery of voiding .

Primary Outcome Measures

Name	Time	Method
failure rate of a limited catheterization duration of 3 hours post- operative	at three hours post surgery	• The failure rate of a limited catheterization duration of 3 hours post- operative is defined by a need of recatheterizatrion within 24 hours post- GL with PVP XPS 180W . The catheterization remains indicated in case of macroscopic hematuria RAU or if no natural urination is possible

Secondary Outcome Measures

Name	Time	Method
The duration of recatherization	during 24 hours hospitalisation	The duration of recatherization is regarded as the total cumulative duration of catheterization regardless of the number of attempts for removale when it is a failure. The average duration of resondage counts only recatheterizations occurring in the first week which may be considered as due to PVP with GL XPS 180W followed by a shortened catheterization of 3 hours post- operatively . The duration of recatherization is defined from the time when it was done in thefirst week post- operative until urinary recovery
Total dose of energy	during 24 hours hospitalisation	The total dose of energy delivered to the tissue induring the intervention will be expressed and collected by means of the instrumentation of the GL-XPS console.
