Bipolar Plasma Enucleation of the Prostate: 5 Years Outcomes.

Background: Aim of our study is to assess outcomes and safety of button bipola transurethral enucleation of the prostate (B-TUEP) in patients with lower urinary tract symptoms (LUTS) caused by benign prostatic enlargement (BPE) in a single-center cohort study. Materials and Methods: All patients with LUTS caused by BPE undergoing button B-TUEP between May 2012 and December 2013 were prospectively enrolled in our study. Data on clinical history, physical examination, urinary symptoms, erectile function, uroflowmetry, and prostate volume were collected at 0, 1, 3, 6, 12, 24, 36, 48, and 60 months. Early and long-term complications were recorded. Results: Overall 50 patients were enrolled at baseline. Nine patients were excluded during the 5 years. All patients completed the procedure without severe complications. In terms of outcomes, improvement in International Prostate Symptom Score (IPSS) were sustained for all 5 years and mean difference from baseline at 5 years was 17 points. As well, improvements in Qmax (maximum urinary flow rate) were sustained for all 5 years and mean improvement at 5 years was 16 mL/second. Erectile function was slightly improved after surgery and maintained for the following 5 years. Conclusions: Our single-center study suggests that B-TUEP may have excellent outcomes at 5 years with no recurrence. Further multicentre studies should confirm our results.

Bipolar plasma enucleation of the prostate vs. open prostatectomy in large benign prostatic hyperplasia: a single centre 3-year comparison.

BACKROUND: Aim of our study is to compare the surgery outcomes and safety of button bipolar enucleation of the prostate vs. open prostatectomy in patients with large prostates (> 80 g) in a single-centre cohort study. MATERIALS AND METHODS: All patients with lower urinary tract symptoms due to benign prostatic enlargement undergoing button bipolar enucleation of the prostate (B-TUEP) or open prostatectomy (OP) between May 2012 and December 2013 were enroled in our study. Data on clinical history, physical examination, urinary symptoms, erectile function, uroflowmetry and prostate volume were collected at 0, 1, 3, 6, 12, 24 and 36 months. Early and long-term complications were recorded. RESULTS: Overall, 240 patients were enroled. Out of them 111 patients (46%) performed an OP and 129 patients (54%) performed a B-TUEP. In terms of efficacy, both procedures showed durable results at three years with a reintervention rate of 7.5% in the OP group and 5% in the B-TUEP group. In terms of safety, B-TUEP presented less high-grade complications when compared with OP. CONCLUSIONS: In our single-centre study, B-TUEP represents a valid alternative to OP with excellent outcomes at three years. Further multicentre studies should confirm our results.

Narrow Band Imaging reduces persistence of cancer in patients with pT1 high grade bladder cancer.

PURPOSE: To evaluate persistence rate on repeated transurethral resection of the bladder (re-TURB) 6 weeks after the first TURB in patients with pT1HG disease undergoing resection of the margins and bed on Narrow Band Imaging. MATERIALS AND METHODS: A consecutive series of patients undergoing TURB and a diagnosis of pT1 high grade disease were prospectively enrolled. On initial TURB patients underwent classic white light resection of the tumour followed by narrow band image (NBI) resection of margins and bed. After 6 weeks from the initial TURB, patients underwent a re-TURB under white light. Persistence rates on re-TURB were recorded. RESULTS: Overall 797 patients underwent TURB, out of them 126 patients with pT1 high grade disease were included in the study. The total number of lesions was 226 meaning 1.79 lesions per patient. On re-TURB 24/126 (19%) of the patients presented residual disease with a total of 28/226 (12%) lesions identified. All these patients presented a pTa residual disease. Out of them 8/21 (38%) presented bladder cancer on the resection bed and 13/21 (62%) presented bladder cancer on margins. CONCLUSION: Narrow Band Imaging trans-urethral resection of the bladder is an oncological effective procedure in the treatment of pT1HG disease. The procedure has a 19% of persistence rate which is inferior when compared to the available evidence on white light TURB. Further multicenter studies are needed in order to validate our results.

A very rare case of adult-type granulosa cell tumor.

Granulosa cell tumor (GST) of the testis is a rare neoplasm. Here we describe a case of an adult type GST. More than a year after surgical treatment, without any other treatment, the patient is alive without sign of disease.

Low-cost semirigid ureteroscopy is effective for ureteral stones: experience of a single high volume center.

AIM OF THE STUDY: To demonstrate how, in a center with a large number of patients, as our center is, it is possible to perform ureterolithotripsy using a limited set of instruments. METHODS: We evaluated medical charts of our center related to semirigid ureteral ureteroscopy (URS) with ureterolithotripsy using Holmium laser performed from July 2004 to July 2011. Overall, 658 URS for ureteral stones were performed in 601 patients, of which 204 in proximal ureter (31%), 86 in the mid (13.06%) and 368 (57.76%) in the distal ureter. In 504 patients (76.5%) ureterohydronephrosis (Grade II-III) was observed. In 57 patients (8.6%), we performed a bilateral approach at the same time, but most patients had a solitary distal ureteral stone. 106 patients (16.1%) had more than one stone in their distal ureter and 96 (14.8%) had a proximal ureteral stone treated in the same surgery as well. RESULTS: The overall stone-free rate for ureteral stones was 86.1% (567/658). Success rates for proximal, medial and distal ureteral stones were 68.13% (139/204 patients), 84.8% (73/86 patients) and 96.4% (355/368 patients), respectively. One hundred and twenty patients (18.3%) required additional surgical treatment for their stones beyond the initial URS, including a second URS in 97 patients (14.74%) and URS plus Retrograde Intra-Renal Surgery (RIRS) in 23 patients (3.54%). The overall stonefree rate after the second treatment was 99.3%. Intra-operative complications accounted for 5.92% and consisted of ureteral perforations in 16 pts (2.4%), erosions of urothelium leading to significant bleeding in 15 pts (2.27%), severe pain in 4 pts (0.6%), fever in 3 pts (0.45%) and one case of ureteral avulsion (0.15%). CONCLUSIONS: This study demonstrates that the use of Holmium laser lithotripsy is a safe and effective means of treating ureteral stones regardless of sex, age, stone location, or stone size. The instrumentation we used was extremely limited, in order to reduce costs related to the procedure to an absolute minimum whilst maintaining the two quality indicators for the procedure, namely success rate and length of hospitalisation (86.1% and 34 hours).

Comparative randomized study on the efficaciousness of endoscopic bipolar prostate resection versus monopolar resection technique. 3 year follow-up.

OBJECTIVE: Transurethral resection of the prostate (TURP) is the current optimal thera- py for the relief of bladder outflow obstruction, with subjective and objective success rate of 85 to 90%. Aim of this study was to evaluate efficacy and safety of Plasmakinetic ener- gy (Gyrus electro surgical system), which produces vaporization of tissue immersed in isotonic saline against standard monopolar transurethral resection of the prostate. METHODS: From January 2002 to April 2002, 160 consecutive patients, who had low urinary tract symptoms (LUTS) of benign prostatic hyperplasia (BPH) were enrolled in this study. Patients were randomised to undergo bipolar TURP (80 patients) or monopolar TURP (80 patients). Preoperative work-up was assessed by administering IPSS, IIEF-5 and Qol questionnaires. All patients were submitted to uroflowmetry, transrectal ultrasound (TRUS), post-voidal residual urine measurement and PSA determination. In the two groups, IPSS, IIEF-5 and Qol, uroflowme- try, TRUS, post-voidal residual urine measurement, PSA determination and number of reopera- tions were evaluated at 1, 3, 6, 12, 18, 24, 30 and 36 months follow up, and then every year. Furthermore, in both groups operative time, resected tissue weight and perioperative complica- tions were analysed. Total postoperative catheter time, total post-operative hospital stay, haemo- globin loss were also recorded in the two groups. RESULTS: Comparative data on IPSS symptom score, IIEF-5, Qol, PSA, peak urinary flow rate and post-void residual urine volume were similar in the two groups but showed a significant improve- ment respect to baseline values. The postoperative haemoglobin levels, postoperative catheteri- zation time, hospital stay and 3-year overall surgical re-treatment-free rate were significantly better in the bipolar group. CONCLUSIONS: Bipolar TURP has a comparable outcome to standard monopolar TURP at short and medium term regard to subjective and objective outcome measurements. Its impact on blad- der outlet function is also similar to that of monopolar TURP. Improvement in IPSS, Qol index, IIEF-5, Qmax and post-void residual urine volume were comparable in both group denoting sim- ilar efficacy of the techniques.

A case of angiomyolipoma of the spermatic cord and testicle.

Angiomyolipomas (AML) are mesenchymal tumors of the kidney consisting of varying proportions of vascular, immature smooth muscle and mature fat cells. A rare case of testicular AML is described. A 53 year old male with a history of congenital motor defects, mental retardation, and hypertension, presented to the emergency room with sudden onset, severe left testicular pain. Scrotal sonography demonstrated an hypoechoic mass in the patient's left testicle. The patient was offered and underwent a trans-inguinal exploration of the left testicle which ended in a left inguinal orchiectomy. Pathologic examination of the mass revealed medium to large calibre thick-walled blood vessels with ectatic lumina, surround by sclerotic, fibrous smooth muscle bundles in a fatty milieu. Immunohistochemistry of the lesion demonstrated positive staining for smooth muscle actin (SMA+) and endothelial marker CD34. The lesion did not, however, stain positively for smooth muscle antigen S100 or melanocytic antigen HMB-45.

Saturation biopsy technique increase the capacity to diagnose adenocarcinoma of prostate in patients with PSA < 10 ng/ml, after a first negative biopsy.

OBJECTIVE: Aim of this study was to evaluate if saturation biopsy (SB) technique increases the cancer detection rate in patients with PSA < 10 ng/ml, after a first negative biopsy. MATERIAL AND METHODS: From January 2004 to January 2006, 780 patients underwent prostate ultrasound guided transrectal (UGT) core biopsy: 186 (23.8%) presented prostate cancer (PCa) while 594 pts (76.2%), were disease free. For 1 year all the patients with no evidence of cancer were observed according to a follow-up schedule including PSA every 3 months and DRE every 6 months. During this period 140 patients showed an increase of PSA (< 10 ng/ml) or a low PSA free/total. This group underwent a second prostate UGT core biopsy with SB technique. In all the patients we evaluated PCa detection rates (DR) according to the PSA range. We also checked peri/post-operative complication rate (total post-operative hospitalization time, haemoglobin loss, catheterisation rate, pain rate, QOL). RESULTS: Of the 140 patients 50 (35.7%) had PCa showing a Gleason score (GS) of 4 or 5 in 26%, 6 or 7 in 75% and 8 to 10 in 9% respectively. Sectors apical biopsies carried out in the anterior horn of peripheral zone tissue presented over 70% (35 patients) of cancer detection rate. Rectal bleeding was the major common complication. Cancer was clinically significant in 47 patients (94%) but 34 (68%) presented an organ confined disease after radical surgery. CONCLUSIONS: SB technique increases of 35.7% the cancer detection rate (DR) in patients with PSA < 10 ng/ml, after a first negative biopsy, showing a higher positivity (70% PCaDR) if the SB included the anterior horn of peripheral zone tissue. No significantly pain and side effects were observed.

Comparative randomized study on the efficaciousness of treatment of BOO due to BPH in patients with prostate up to 100 gr by endoscopic gyrus prostate resection versus open prostatectomy. Preliminary data.

OBJECTIVES: With the advent of medical management and minimally techniques for benign prostate hypeplasia (BPH), invasive surgical procedures such open prostatectomy (OPSU) have become less common, although selected patients may still benefit from open prostatectomy. Aim of this study was to evaluate efficacy and safety of Bipolar TURP (Gyrus electro surgical system) versus standard open prostatectomy in patients with lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO) with markedly enlarged glands refractory to medical therapy. METHODS: From January 2003 to January 2004, 140 patients affected by mild-severe LUTS, secondary to BOO from BPH, refractory to medical therapy, with markedly enlarged glands, were randomized in two groups (1:1), and subjected to open prostatectomy (OPSU) carried out with traditional method (Bracci Thechnique) versus transurethral resection of the prostate (TURP) utilizing the bipolar methodology. Preoperative work-up included IPSS, IIEF-5 and Qol questionnaires. All patients were submitted to uroflowmetry, transrectal ultrasound (TRUS), measurament of postvoidal residual urine and PSA determination. IPSS, IIEF-5 and Qol, uroflowmetry, TRUS, measurement of post-voidal residual urine, PSA determination and number of reoperations were evaluated at 1, 3, 6, 12, 18, 24, 30 and 36 months. Operative time, resected tissue weight and perioperative complications were also registered. Total post-operative catheter time, total postoperative hospital stay, haemoglobin loss were recorded in the 2 groups. RESULTS: Comparative data on IPSS symptom score, IIEF-5 and Qol, PSA, peak urinary flow rates and post-void residual urine volume in the 2 groups were similar but showed a significative improvement with respect to baseline value. Postoperative haemoglobin levels, postoperative catheterization, hospital stay and 3-yr overall surgical re-treatment-free rate were significantly better in the Bipolar group. CONCLUSIONS: In the treatment of LUTS due to bladder outlet obstruction (BOO) with markedly enlarged glands refractory to medical therapy, Bipolar TURP has a comparable outcome to open prostatectomy at short and medium term according to both subjective and objective outcome measures.

Risk of prostate cancer at first saturation re-biopsy in a patient with previous diagnosis of HGPIN.

INTRODUCTION: It is advisable to submit a patient with isolated HGPIN to re-biopsy every 3-6 months, performing an increasing number of samples in order to increase the detection rate. The aim of this study is to evaluate if the use of saturation needle biopsy technique may increase this rate. MATERIALS AND METHODS: From January 2004 to June 2006, 780 patients with hypoecogenic nodule at TRUS and/or PSA values between 2.5 and 10 ng/ml, underwent TRUS 10-core prostate needle biopsy, performed by the same operator Isolated HGPIN was detected in 26 cases (3.3%). Within a year all these patients underwent saturation needle re-biopsy. This procedure consisted of 24 samples obtained using a tru-cut needle 18 G under soft anesthesia by a major opiate. All the patients received a single dose of Levofloxacin per os before the biopsy and for the following 2 days. RESULTS: Prostate cancer was found in 8 (33.3%) of the 24 eligible patients: 40% showed a Gleason Score 6 and 60% > 7. Concerning PSA, we observed 35% of neoplasms for values between 2.5 and 3.9 ng/ml and the remaining 65.0% for values between 4.0 and 9.9 ng/ml. CONCLUSIONS: The use of saturation needle biopsy allowed to detect 30.8% of prostatic cancer performing the first re-biopsy within a year. This result does not differ from others obtained with 8-10 cores techniques, therefore the indication of the 24-cores procedure should be limited to carefully selected patients with a high risk of developing cancer after that other techniques had not been successful.
