Water vapor therapy (Rezum) for lower urinary tract symptoms related to benign prostatic hyperplasia: early results from the first Italian multicentric study.

PURPOSE: Rezum is the latest developed minimally invasive treatment for benign prostatic hyperplasia (BPH). We aimed to carefully assess the functional outcomes of patients treated with Rezum for BPH. METHODS: We prospectively followed 135 consecutive patients treated by Rezum at 5 institutions from June 2019 to August 2020. The International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI SF), the Overactive Bladder Questionnaire-Short Form (OAB-q SF) score, the International Index of Erectile Function (IIEF-5) and questions 9 and 10 to assess ejaculatory dysfunction were recorded. Election criteria were age > 18, no prior prostate interventions, IPSS ≥ 13, post-void residual ≤ 250 mL, prostate volume between 30 and 120 cc. RESULTS: The median operative time was 10.5 (IQR 8.7-15) min. All patients were dismissed few hours after surgery with indwelling urinary catheter that was removed after a median of 7 (IQR 7-10) days. A significantly decrease of IPSS from baseline at first (p = 0.001) and third (p < 0.0001) month after surgery was reported. No difference was reported in terms of ICIQ-UI SF score postoperatively. A mild reduction of the OAB-q SF score was reported at 1 month from surgery (p = 0.06) that turned significant at 3 months postoperatively (p < 0.0001). A slight but statistically significant increase of the IIEF-5 score was reported from baseline at 6 months (p = 0.04). Postoperatively, patients reported a significantly decrease of ejaculatory dysfunction after alpha-blocker interruption. CONCLUSION: Rezum treatment is a feasible minimally invasive option for patients with BPH symptoms and showed optimal early functional outcomes.

Our experience with nifedipine and prednisolone as expulsive therapy for ureteral stones.

OBJECTIVES: We evaluated the effect of nifedipine associated with prednisolone in ureteral stone passage. MATERIAL AND METHODS: In our department we enrolled 50 patients with radiopaque ureteral stones. Stone size was 15 mm or less. The patients were divided into two groups: group I included 25 patients who received 30 mg oral treatment of slow-release nifedipine (for a maximum of 20 days) and 25 mg of prednisolone (for a maximum of 10 days) daily. Group II was made up of 25 patients who received 25 mg of prednisolone daily. On request, both groups could use non-steroidal anti-inflammatory drugs. RESULTS: The mean expulsion time was 6 days in group I and 10 days in group II. The average stone size was 12 mm in group I and 12.8 mm in group II. Six patients suspended therapy in group I (5 erythema, 1 stomachache), and seven in group II (3 because of intolerable pain, 4 stomachache). The expulsion success rates were 68% in group I and 81% in group II. CONCLUSIONS: For ureteral stones that do not cause an emergency situation, such as obstructive uropathy, infection or intolerable pain, we suggest expulsive medical treatment with nifedipine and prednisolone, if there are no contraindications to drug use.

Role of Ca 15-3 in patients with biochemically suspected prostate cancer and multiple negative ultrasound-guided prostate biopsies.

Ca 15-3 is an aspecific tumor marker characteristic of cancer proliferation. Elevated serum levels seem to be closely correlated with cancer progression in non-urological tumors. This study assessed the role of Ca 15-3 as an aspecific tumor marker in patients with borderline prostate-specific antigen (PSA) biochemically suspected of prostate cancer (PCa) and with multiple negative prostate biopsies. The study is based on prospective analysis of 103 patients: (a) 33 patients (group A) presented lower urinary tract symptoms secondary to BPH with normal serum PSA values, DRE and TRUS negative for suspected PCa; (b) 31 patients (group B) with histologically diagnosed PCa; (c) 39 patients (group C) with borderline serum PSA values, DRE and TRUS normal, two ultrasound (US)-guided random prostate biopsies negative for PCa. Ca 15-3 was determined in the entire study series by the IRMA method, using as range the values proposed for the investigated non-urological tumors (38 UI/l).Ca 15-3 was within normal range in all group A patients (control), while the values were elevated in 27/31 of group B patients (PCa) and in 11/39 of group C (PCa suspected) patients. A third biopsy was performed in all 39 group C patients with borderline PSA and it was PCa-positive in 13 patients (33.3%, subgroup C3). In this series Ca 15-3 was increased in 9 of 13 patients (subgroup C3alpha), while the remaining four patients (subgroup C3beta) presented values within the normal range. On 26 group C patients who were negative for PCa to third biopsy (subgroup C4), 24 patients had Ca 15-3 levels within normal range (subgroup C4alpha) with histologic findings of BPH in 23 cases and granulomatous chronic prostatitis in one case, while two patients (subgroup C4beta) had elevated Ca 15-3 concentrations associated with lymphoplasmacytic chronic prostatitis. We hypothesize that Ca 15-3, as a specific tumor marker, could be an interesting and inexpensive second step diagnostic tool for PCa in patients with borderline PSA and multiple negative prostate biopsies, as it could indicate whether a repeated biopsy should be performed in a short time, having excluded other concomitant tumors. However, further prospective studies will be necessary to confirm this hypothesis.
