Brief summary

The goal of this single-centre prospective randomized clinical trial is to compare the post-operative use of temporary prostatic stent (Group 1) vs indwelling catheter (Group 2) in patients undergoing cryotherapy for targeted therapy of localized prostate cancer, transurethral water vapor energy ablation (REZUM) or transperineal laser ablation of the prostate with EchoLaser™ system for the treatment of benign prostatic hyperplasia (BPH) The main questions are: * Difference in quality of life, Lower Urinary Tract Symptoms (scored with IPSS, International Prostate Symptom Score), urinary continence symptoms (scored with International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, ICIQ-UI-SF) and patient satisfaction between indwelling catheter and temporary prostatic stent (Exime®) score with a non-validated questionnaire (Stent/catheter-related urinary symptoms questionnaire) * Difference in side effects and complications between indwelling catheter and temporary prostatic stent (Exime®) A total 120 of patients will be enrolled (Group 1: 60; Group 2: 60) with a 1:1 randomization ratio. The follow-up duration will be 6 months.

Intervention model description

Prospective randomized clinical trial divided in 3 cohorts: HERMES\_CRYO (cryotherapy for targeted therapy of localized prostate cancer), HERMES\_REZUM \[water vapor energy ablation for the treatment of benign prostatic hyperplasia (BPH)\], and HERMES\_LASER \[ELESTA ECHOLASER® for the treatment of benign prostatic hyperplasia (BPH)\]. In each cohort, two arms will be compared: temporary prostatic stent vs indwelling catheter with a 1:1 randomization ratio.

Design outcomes

Primary

MeasureTime frameDescription
Device-related quality of life1 weekEvaluation of impact on patient quality of life associated with the urinary device will be based on the sixth question (Q6) of a non validated questionnaire (Stent/catheter-related urinary symptoms questionnaire), defined as: Q6: How much has the bladder catheter/Exime affected your quality of life? Quantitative answer, ranging from 0 to 10. Being zero, not affected; and being ten, very affected

Secondary

MeasureTime frameDescription
Device-related patient satisfaction1 weekEvaluation of satisfaction of patients associated with the device will be based on the seventh question (Q7) of a non validated questionnaire (Stent/catheter-related urinary symptoms questionnaire), defined as: Q7. What is your degree of satisfaction while wearing the catheter/Exime®? Quantitative answer, ranging from 0 to 10. Being zero, not satisfied at all; and being ten, completely satisfied
Device-related Lower Urinary Tract Symptoms (LUTS)From device-placement to 6 months after treatmentEvaluation of impact of the device on LUTS will be based on a validated questionnaire administered before the device-placement, at device-removal, at 4 weeks and finally at 6 months after treatment: \- International Prostate Symptom Score (IPSS), min 0 - max 35 points, in which higher values are associated with worsening urinary symptoms
Occurence of perioperative events (< or = 24h after treatment)1 post-operative dayEvaluation of perioperative events (\< or = 24h after treatment) defined as complications (classified according to the Clavien - Dindo scale), presence of haematuria, pain (based on visual analogue pain score), occurence of acute urinary retention or need to perform urinary catheter bladder washout.
Device-related urinary side effects1 weekEvaluation will be based on the first five questions (Q1 - Q5) of a non validated questionnaire with quantitative answers ranging from 0 to 10, defined as: Q1:How much urine leakage have you had while carrying the bladder catheter or the Exime® device? (0: none -\> 10 a lot of leakage = need to use several diapers) Q2. How much pain, discomfort or spasms have you had in relation to the catheter/Exime®? (0: none -\> 10: a lot of pain = need for prescribed analgesia) Q3. How much bleeding have you had with urine while wearing the catheter/Exime®? (0: none -\> 10: a lot of bleeding = need for change of clothing) Q4. How much has the urine been different? (darker than usual, worse odor, or sediment)? (0: nothing -\> 10: very strong odor, very dark urine, presence of lumps) Q5. Have you had any problems in handling the catheter? (0: no problems at all -\> 10: many problems)
Overall satisfaction outcomes4 weekEvaluation of overall satisfaction will be based on the question How satisfied are you overall with the treatment you have received? (Quantitative answer, ranging from 0 to 10. Being zero, not satisfied at all; and being ten, completely satisfied) administered at 4 week post-treatment.
Urine flow rateFrom device-placement to 6 months after treatmentMaximal flow rate \[Q max (ml/s)\] will be evaluated performing a uroflowmetry at baseline, at week 4, and finally at 6 months after treatment.
Device-related continence symptomsFrom device-placement to 6 months after treatmentEvaluation of impact of the device on continence symptoms will be based on a validated questionnaire administered before the device-placement, at device-removal, at 4 weeks and finally at 6 months after treatment: \- International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF): min 0 - max 21 points, the higher the score, the more severe is the urinary incontinence, but there is no normal score.
Occurrence of postoperative events (>24h-1week)1 weekEvaluation of postoperative events (\>24h-1week) defined as acute urinary retention or need to perform urinary catheter bladder washout, need to change urinary catheter or presence of urinary tract infection (presence of fever or need to change antibiotic therapy) and others complications (classified according to the Clavien - Dindo scale)
