BPH

Brief summary

This is a prospective data collection of subjects using blude diode laser for the treatment of BPH.

Detailed description

This is a prospective single-arm study evaluating the outcome of blue diode laser vaporization. The energy from a 450nm blue laser vaporization will be used for the treatment of BPH. The study period for each patient is 1 year. Recruited subjects will then be followed up at 3 months, 6 months and 12 months after operation. Blood tests, urine tests, ultrasound for prostate volume assessment, uroflowmetry and the same set of questionnaires will be performed again during follow-up for assessing the clinical progress. Any adverse event and unplanned admission will also be documented.

Interventions

DEVICEBlue diode laser

All procedures would be performed under spinal or general anaesthesia. Blue diode laser vaporization would be performed according to the standard approach for the obstructing prostate

Design outcomes

Primary

MeasureTime frameDescription
Urinary symptoms measured by International Prostate Symptom Score (IPSS) scoreBaseline, 1 month, 3 months, 6 months, 12 monthChange in total scores in International Prostate Symptom Score (ranges from 0 to 35) questionnaires. The higher score, the more worse symptom
Change in urodynamic in uroflowmetryBaseline, 1 month, 3 months, 6 months, 12 monthChange in urodynamic function assessed by uroflowmetry

Secondary

MeasureTime frameDescription
Hospital stayPeri-operative periodDuration of hospital stay in hour since completion of surgery
Operation TimeIntra-operationDuration of the operation
Need of post operative irrigationPeri-operative periodNeed of post operative irrigation
Verbal dysuria scoreFirst day after catether removalIt is assesed by a scale from 0-10; the higher score the more worse dysuria
Incidence of unplanned clinic okr hospital attendance90 days since completion of surgeryNumber of unplanned clinic or hospital attendance after surgery
Transfusion rate1 monthNo of patient need transfusion
Erectile function measured by International Index of Erectile Function 5-item version (IIEF-5) scoreBaseline, 1 month, 3 months, 6 months, 12 monthChange in International Index of Erectile Function 5 questionnaire score (ranges from 0 to 25). The higher score, the more worse symptom
Ejaculatory function measured by MSHQ-EjD-SF (function and bother) scoreBaseline, 1 month, 3 months, 6 months, 12 monthChange in MSHQ-EjD-SF questionnaire score (Range from 1-15 for function and and 0-5 for bother). The higher score, the more worse symptom
Prostate Specific Antigen (PSA) changeBaseline, 1 month, 3 months, 6 months, 12 monthPSA change after treatment
Adverse events (AE) and serious adverse events (SAE) related to the treatmentBaseline, 1 month, 3 months, 6 months, 12 monthThe severity of AE is grade by Clavien-Dindo classification.
Patient quality of lifeBaseline, 1 month, 3 months, 6 months, 12 monthAssessed with the EQ-5D-5L questionnaire from 0-100, the higher the score the better in quality of life
Catheter time1 month, 3 month, 6 month, 12 monthDuration of catheter time in hour since completion of surgery
