Transperineal laser ablation of the prostate as a treatment for benign prostatic hyperplasia and prostate cancer: The results of a Delphi consensus project.

Objective: To evaluate transperineal laser ablation (TPLA) with Echolaser® (Echolaser® TPLA, Elesta S.p.A., Calenzano, Italy) as a treatment for benign prostatic hyperplasia (BPH) and prostate cancer (PCa) using the Delphi consensus method. Methods: Italian and international experts on BPH and PCa participated in a collaborative consensus project. During two rounds, they expressed their opinions on Echolaser® TPLA for the treatment of BPH and PCa answering online questionnaires on indications, methodology, and potential complications of this technology. Level of agreement or disagreement to reach consensus was set at 75%. If the consensus was not achieved, questions were modified after each round. A final round was performed during an online meeting, in which results were discussed and finalized. Results: Thirty-two out of forty invited experts participated and consensus was reached on all topics. Agreement was achieved on recommending Echolaser® TPLA as a treatment of BPH in patients with ample range of prostate volume, from <40 mL (80%) to >80 mL (80%), comorbidities (100%), antiplatelet or anticoagulant treatment (96%), indwelling catheter (77%), and strong will of preserving ejaculatory function (100%). Majority of respondents agreed that Echolaser® TPLA is a potential option for the treatment of localized PCa (78%) and recommended it for low-risk PCa (90%). During the final round, experts concluded that it can be used for intermediate-risk PCa and it should be proposed as an effective alternative to radical prostatectomy for patients with strong will of avoiding urinary incontinence and sexual dysfunction. Almost all participants agreed that the transperineal approach of this organ-sparing technique is safer than transrectal and transurethral approaches typical of other techniques (97% of agreement among experts). Pre-procedural assessment, technical aspects, post-procedural catheterization, pharmacological therapy, and expected outcomes were discussed, leading to statements and recommendations. Conclusion: Echolaser® TPLA is a safe and effective procedure that treats BPH and localized PCa with satisfactory functional and sexual outcomes.

Combined laparoscopic pyelolithotomy and endoscopic pyelolithotripsy for staghorn calculi: long-term follow-up results from a case series.

PURPOSE: Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management. We report our experience with a combined approach of laparoscopic pyelolithotomy and endoscopic pyelolithotripsy, the stone clearance rate, and long-term, follow-up outcomes. METHODS: From June 2012 to October 2014, nine adult patients with large staghorn renal calculi (mean size, 7.2 cm; range, 6.2-9.0 cm) underwent a combined laparoscopic and endoscopic approach. The technique comprised laparoscopic pyelolithotomy and holmium-YAG laser stone fragmentation with the use of a flexible cystoscope introduced through a 12 mm trocar. RESULTS: The average operative time was 140 min (range, 90-190 min). The mean estimated hemoglobin loss was 0.6 mmol/l (range 0.5-0.7 mmol/l). None of the patients required an open- surgery conversion. The mean hospital stay was 4 days (range, 2-6 days). A computed tomography urogram control at 6 months of follow up did not show any stone recurrence. CONCLUSIONS: Laparoscopic pyelolithotomy combined with endoscopic pyelolithotripsy could be a therapeutic option in cases where mini-invasive procedures, that is, extracorporeal shock wave lithotripsy, ureteroscopic lithotripsy, and percutaneous nephrolithotomy (PCNL) have failed. This technique has a high stone-clearance rate (75-100%) comparable with open surgery and PCNL. However, it could be technically demanding and should be performed by skilled laparoscopy surgeons.

A novel combination of triple metachronous malignancies of the kidney, oropharynx and prostate: A case report.

Synchronous or metachronous malignancies are a rare event, with an incidence rate that increases with age. The present study reports the case of a 70-year-old Caucasian male who was referred to the outpatient office of the Urology Unit, Sapienza University of Rome (Latina, Italy) due to lower urinary tract symptoms. An abdominal ultrasound investigation was performed that demonstrated the presence of a right renal mass. The patient underwent right radical nephrectomy, which resulted in the definitive diagnosis of clear cell type renal cell carcinoma. The patient was eventually diagnosed with triple primary metachronous cancer consisting of renal clear cell carcinoma, prostate adenocarcinoma and squamous cell carcinoma of the oropharynx (palatine tonsil). To the best of our knowledge, this combination of primary neoplasms has not previously been documented.

Laparoscopic radical prostatectomy after previous transurethral resection of prostate using a catheter balloon inflated in prostatic urethra: Oncological and functional outcomes from a matched pair analysis.

OBJECTIVES: To explore the surgical, oncological and functional outcomes of laparoscopic radical prostatectomy in patients who have undergone transurethral resection of the prostate, using a catheter balloon inflated in the prostatic urethra. METHODS: A total of 25 patients were randomly assigned to the no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group (n = 12) and the with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group (n = 13). Two matched pairs analyses were carried out to identify the 12 (control A) and 13 (control B) surgery-naïve patients. The outcomes were compared between the groups with previous transurethral resection of the prostate (no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy groups) and the controls. The rate of intra- and postoperative complications was assessed. The International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and the International Index of Erectile Function 5 were used for symptoms evaluation. RESULTS: The mean blood loss was higher in patients submitted to transurethral resection of the prostate, with statistically insignificant reduced blood loss in the with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group. The no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group had longer operative time compared with both the with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and control A groups (P < 0.05). International Index of Erectile Function 5 showed a significant difference between no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and its control group; the International Consultation on Incontinence Questionnaire showed a statistically significant difference (P < 0.05) between the no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and control A groups. CONCLUSION: The use of a catheter balloon inflated in the prostatic urethra seems to facilitate laparoscopic radical prostatectomy in patients with previous transurethral resection of the prostate, ultimately reducing the rate of perioperative complications. These findings warrant further investigation on a larger case series with a longer follow up.

Can daily intake of aspirin and/or statins influence the behavior of non-muscle invasive bladder cancer? A retrospective study on a cohort of patients undergoing transurethral bladder resection.

BACKGROUND: This study aimed to evaluate the behavior of non-muscle-invasive bladder cancer (NMIBC) in patients submitted to transurethral bladder resection (TURB) comparing subjects in chronic therapy with aspirin, statins, or both drugs to untreated ones. METHODS: This retrospective study was conducted on 574 patients diagnosed with NMIBC who underwent TURB between March 2008 and April 2013. The study population was divided into two main groups: treated (aspirin and/or statins) and untreated. The treated group was further divided into three therapeutic subgroups: Group A (100 mg of aspirin, daily for at least two years); Group B (20 mg or more of statins, daily for at least two years); and Group C (100 mg of aspirin and 20 mg of statins together). The mean follow-up of patients was 45.06 months. RESULTS: No significant differences were observed among the different groups at baseline. On multivariate analysis, statin treatment, smokers and high stage disease (T1) achieved the level of independent risk factor for the occurrence of a recurrence. When patients were stratified according to the different treatment; patients treated with statins (Group B) presented an higher rate of failure (56/91 patients; 61.5%) when compared to Group A (42/98 patients; 42.9%), Group C (56/98; 57.1%) and (133/287 patients; 46.3%). This difference corresponds to a significant difference in recurrence failure free survival (p = 0.01). CONCLUSIONS: Our results suggest that long-term treatment with aspirin in patients with NMIBC might play a role on reducing the risk of tumor recurrence. In contrast, in our investigation data from statins and combination treatment groups showed increased recurrence rates. A long-term randomized prospective study could definitively assess the possible role of this widely used drugs in NMIBC.

Videourodynamic evaluation of intracorporeally reconstructed orthotopic U-shaped ileal neobladders.

OBJECTIVE: To study the functional outcomes of 30 patients who had previously undergone laparoscopic radical cystectomy with intracorporeal orthotopic ileal neobladder reconstruction using videourodynamic (VUDM) assessment 180 days postoperatively. METHODS: Between November 2010 and December 2013, 30 male patients had undergone laparoscopic radical cystectomy with bilateral standard pelvic lymphadenectomy and pure laparoscopic orthotopic ileal U-shaped neobladder diversion. The demographic data were as follows: median age, 67 years (range, 62-79); body mass index, 22.3 kg/m(2) (range, 16-26.1 kg/m(2)); and mean American Society of Anesthesiologists score 2.2 (range, 1-3). Functional outcomes were assessed performing a standard VUDM study combined with perineal floor electromyography 180 days postoperatively. RESULTS: VUDM evaluations showed good functional outcomes of the reservoirs. Mean maximal neobladder capacity was 287 mL (range, 210-335 mL). Residual peristaltic activity was observed in all the individuals evaluated; however, only 9 of 30 individuals (30%) displayed severe peristaltic activity. Six of these 9 individuals (66.6%) experienced urinary leakage during these contractions. Mean postvoid residual volume was 44 mL (range, 0-105 mL), and peak flow rate was 13.9 mL/s (range, 9.7-29.2 mL/s). The Valsalva maneuver was positive in 5 of 30 subjects (17%). Bladder morphology assessed during contrast cystography showed the desired U-shape in all cases. Ureteral reflux was observed in 7 of 30 individuals (23.3%). CONCLUSION: Based on VUDM, our study shows that U-shaped ileal neobladders achieved by a totally laparoscopic approach obtained good functional outcomes. These findings support the evidence that a minimally invasive approach does not impose technical limitations that negatively impact the surgical results.

Endoscopic rendezvous procedure for ureteral iatrogenic detachment: report of a case series with long-term outcomes.

BACKGROUND AND PURPOSE: Injury to the ureter is the most common urologic complication of pelvic surgery, with an incidence that ranges from 1% to 10%. Most cases of ureteral injuries are related to gynecologic procedures. The ureter is particularly vulnerable to detachment or ligation during hysterectomy because of its position from the lateral edge of the cervix. We report a case series of female patients who underwent the ureteral rendezvous procedure for ureteral detachment. PATIENTS AND METHODS: Between January 2009 and April 2013, 18 ureteral rendezvous procedures were performed for patients with complete detachment. We assessed the operative and clinical outcomes of these patients over a mean follow-up duration of 26.5 months and describe the three most representative cases. RESULTS: The endoscopic rendezvous technique was performed in all cases to manage ureteral detachment. CT urography at discharge and 6 and 12 months after discharge confirmed the restoration of ureteral integrity without any leakage in 66% (12/18) patients, indicated ureteral stenosis in 22% (4/18) patients, and indicated ureteral leakage in 12% (2/18) patients. The overall long-term success rate for all 18 patients was 78% (14/18) at a mean follow-up of 26.5 months. CONCLUSIONS: The endoscopic rendezvous procedure reduces the need for invasive open surgical repair and represents the optimal initial option in patients with iatrogenic ureteral lesions before invasive procedures with higher morbidity are attempted.

Pure intracorporeal laparoscopic radical cystectomy with orthotopic "U" shaped ileal neobladder.

BACKGROUND: Radical cystectomy with pelvic lymph node dissection represents the standard treatment for muscle-invasive, and high-risk non-muscle-invasive bladder cancers. Aim of this study was to report our case series of 30 patients undergoing totally laparoscopic radical cystectomy (LRC) with reconstruction of an intracorporeal orthotopic ileal neobladder. Intra- and perioperative results and the functional and oncological outcomes 9 months after operation are reported. METHODS: Between October 2010 and December 2012, 30 male patients underwent LRC with a pure laparoscopic orthotopic ileal "U"- shaped neobladder diversion. The men had a median age of 67 years, a median body mass index of 22.3, and a mean ASA score of 2.2; they represented various clinical stages of disease. RESULTS: None of the patients required conversion to open surgery, and no perioperative mortalities were reported. The median operating time was 365 min, and the median blood loss was 290 mL, with a transfusion rate of 26.6%. All surgical margins were negative; 8 patients with non-organ-confined disease or positive lymph nodes received adjuvant chemotherapy. Early complications (within 30 days) occurred in 7 patients, and late complications occurred in 6 patients. The mean hospital stay was 9 days. At 9 months after surgery, the daytime continence rate was 83.3% and the nighttime continence rate was 73.3%. CONCLUSIONS: Pure LRC with intracorporeal orthotopic ileal neobladder reconstruction may represent a viable alternative to open radical cystectomy, with a significant reduction in patient morbidity. Future, large, randomized controlled trials with extensive follow-up are needed to confirm our encouraging results.

Are early continence recovery and oncologic outcomes influenced by use of different devices in prostatic apex dissection during laparoscopic radical prostatectomy?

BACKGROUND AND PURPOSE: Treatment of patients with prostate cancer has evolved considerably in the last decade, especially in terms of minimization of the negative impacts on erectile function and continence to ensure good quality of life for treated patients. New surgical devices, such as dissectors and hemostatic scalpels, allow precise definition of the surgical field with finer dissection of the anatomic structures, with subsequent reductions in operative times and better oncologic and functional outcomes. Although monopolar scissors (MS) are still widely used, radiofrequency (RF) and ultrasound (US) scalpels have been introduced recently in laparoscopic radical prostatectomy (LRP). Despite the widespread use of these scalpels, however, few studies have compared these devices in terms of oncologic and functional outcomes after radical prostatectomy. The present study aimed to prospectively assess the impact of MS, RF, and US scalpels on margin status at apex, and recovery of urinary continence and erectile function in patients undergoing extraperitoneal LRP. PATIENTS AND METHODS: A total of 150 men were prospectively enrolled between September 2009 and April 2013 and postoperatively evaluated for continence and clinical factors. RESULTS: There were no differences in terms of operative times (P=0.9433), blood loss (P=0.9681), apical margin positivity (P=0.3965) or postoperative hospital stay (P=0.9257) among the groups. Moreover, no differences in the functional outcome scores, as evaluated by the International Consultation on Incontinence self-administered Questionnaire, at 1, 3, and 6 months postsurgery were observed. CONCLUSION: Our study represents the first evaluation of continence recovery in LRP with respect to different devices used for prostatic apex dissection. We found that the oncologic, functional, and operative outcomes were similar between these different devices during LRP, with no scalpel demonstrating superiority in continence recovery.

Bone metastases from bladder perivascular epithelioid cell tumor - an unusual localization of a rare tumor: a case report.

INTRODUCTION: Perivascular epithelioid cell tumors are mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. This type of tumor is rare but bladder localization is even rarer. CASE PRESENTATION: A case of bone metastatic bladder perivascular epithelioid cell tumor in a 65-year-old Caucasian man treated with surgery and chemotherapy is described and compared with other reports in the literature. CONCLUSIONS: The rarity of perivascular epithelioid cell tumors hinders the development of a standard therapeutic approach, and thus requires case report descriptions. There is a need for cooperative studies to enlarge the case series and establish the best treatment strategy for this rare disease.

Synchronous primary neoplasms of the bladder, skin and breast in a male patient: a case report.

The incidence of multiple primary malignant neoplasms increases with age, reflecting an increase in overall cancer risk in older patients. Cases of two or more concurrent primary cancers are still rare, although its incidence is increasing. Here, we report the case of a 57-year-old man who was referred to our institution with synchronous squamous cell carcinoma of the skin on the forehead, infiltrating ductal carcinoma of the breast, and transitional cell carcinoma of the urinary bladder. To the best of our knowledge, this is the first reported case in literature of this combination of primary neoplasms.

Prospective randomized study of radiofrequency versus ultrasound scalpels on functional outcomes of laparoscopic radical prostatectomy.

BACKGROUND AND PURPOSE: Surgical treatment of patients with prostate cancer currently involves laparoscopic radical prostatectomy (LRP) or robot-assisted LRP. Continence and nerve-sparing procedures in these techniques are supported by dissection and hemostatic surgical devices powered by different types of energy. The aim of this study was to assess recovery of continence and erectile function after laparoscopic extraperitoneal radical prostatectomy comparing two surgical devices for dissection and hemostasis-radiofrequency (RF) and ultrasound (US) scalpels. PATIENTS AND METHODS: A total of 132 men with localized prostate cancer were prospectively enrolled and scheduled for extraperitoneal LRP. Patients were randomly assigned to the RF group (LigaSure; n=66) or the US group (UltraCision; n=66). Outcomes were measured by the self-administered questionnaires (International Consultation on Incontinence Questionnaire-Urinary Incontinence [ICIQ-UI] and International Index of Erectile Function 5 [IIEF 5]) 15 days before surgery, 90 and 180 days after prostatectomy to assess recovery of urinary continence and erectile function. RESULTS: No significant difference was found between the two groups regarding operative time, intra- and perioperative complications, or time of hospital stay. At 180 days after surgery, patients in the RF-treated group showed better recovery in terms of continence and erectile function compared with patients in the US group (ICIQ-UI: p=0.0016; IIEF 5: p=0.0352). CONCLUSIONS: The use of the RF scalpel provided better functional outcomes compared with the US scalpel in patients undergoing extraperitoneal LRP. This might be attributed to the low contiguous damage of those tissues, which are not directly involved in dissection and hemostasis, achieved using the RF device.

A multistep approach to manage Fournier's gangrene in a patient with unknown type II diabetes: surgery, hyperbaric oxygen, and vacuum-assisted closure therapy: a case report.

INTRODUCTION: Fournier's gangrene is an infectious necrotizing fasciitis of the perineum and genital regions and has a high mortality rate. It is a synergistic infection caused by a mixture of aerobic and anaerobic organisms and predisposing factors, including diabetes mellitus, alcoholism, malnutrition, and low socioeconomic status. We report a case of Fournier's gangrene in a patient with unknown type II diabetes submitted to 24-hour catheterization 15 days before gangrene onset. CASE PRESENTATION: The patient, a 60-year-old Caucasian man, presented with a swollen, edematous, emphysematous scrotum with a crepitant skin and a small circle of necrosis. A lack of resistance along the dartos fascia of the scrotum and Scarpa's lower abdominal wall fascia combined with the presence of gas and pus during the first surgical debridement also supported the diagnosis of Fournier's gangrene. On the basis of the microbiological culture, the patient was given multiple antibiotic therapy, combined hypoglycemic treatment, hyperbaric oxygen therapy, and several surgical debridements. After five days the infection was not completely controlled and a vacuum-assisted closure device therapy was started. CONCLUSIONS: This report describes the successful multistep approach of an immediate surgical debridement combined with hyperbaric oxygen and negative pressure wound therapy. The vacuum-assisted closure is a well-known method used to treat complex wounds. In this case study, vacuum-assisted closure treatment was effective and the patient did not require reconstructive surgery. Our report shows that bladder catheterization, a minimally invasive maneuver, may also cause severe infective consequences in high-risk patients, such as patients with diabetes.

Incidental diagnosis of a retroperitoneal schwannoma in a patient with chronic leukemia undergoing prostatic biopsy.

We present a case of retroperitoneal schwannoma incidentally diagnosed in a patient undergoing surgical drainage of a pelvic abscess as a complication of a prostatic biopsy. A 50-year-old male, suffering from lymphatic leukemia, came to our observation due to lichen ruber planus and ejaculatory pain. The patient underwent a trans-perineal ultrasound-guided biopsy of the right seminal vesicle and of a hypoechoic area documented by ultrasonography. 48 hours after the procedure, the patient had developed: cold sores, shortness of breath with dyspnea, and high fever (40°C). The patient was hospitalized, underwent an emergency CT which documented a right presacral and pararectal liquid mass (abscess). The patient underwent emergency laparotomy and drainage of the abscess. The lesion histological examination revealed a retroperitoneal schwannoma with inflammatory phenomena and hyperplasic lymphadenitis. The retroperitoneal schwannoma is a silent disease whose only clinical manifestation coincides with the compression of adjacent anatomical structures. In many cases, the symptoms, even if present, as in this case (ejaculatory pain with compression of the seminal vesicle), are non-specific, thus delaying diagnosis and the therapeutic approach.
