RESUMEN

We compared the perioperative outcomes of open (ORC) vs. robot-assisted (RARC) radical cystectomy in the treatment of pT4a MIBC. In total, 212 patients underwent ORC (102 patients, Group A) vs. RARC (110 patients, Group B) for pT4a bladder cancer. Patients were prospectively followed and retrospectively reviewed. We assessed operative time, estimated blood loss (EBL), intraoperative and postoperative complications, length of stay, transfusion rate, and oncological outcomes. Preoperative features were comparable. The mean operative time was 232.8 vs. 189.2 min (p = 0.04), and mean EBL was 832.8 vs. 523.7 mL in Group A vs. B (p = 0.04). An intraoperative transfusion was performed in 32 (31.4%) vs. 11 (10.0%) cases during ORC vs. RARC (p = 0.03). The intraoperative complications rate was comparable. The mean length of stay was shorter after RARC (12.6 vs. 7.2 days, p = 0.02). Postoperative transfusions were performed in 36 (35.3%) vs. 13 (11.8%) cases (p = 0.03), and postoperative complications occurred in 37 (36.3%) vs. 29 (26.4%) patients in Groups A vs. B (p = 0.05). The positive surgical margin (PSM) rate was lower after RARC. No differences were recorded according to the oncological outcomes. ORC and RARC are feasible treatments for the management of pT4a bladder tumors. Minimally invasive surgery provides shorter operative time, bleeding, transfusion rate, postoperative complications, length of stay, and PSM rate.

RESUMEN

Objectives: To compare surgical and functional outcomes between off-clamp robot-assisted partial nephrectomy with indocyanine-green tumour marking through preliminary superselective embolization and on-clamp robot-assisted partial nephrectomy with intraoperative ultrasound identification of the renal mass. Material and methods: One hundred and forty patients with a single renal mass underwent indocyanine-green fluorescence-guided off-clamp robot-assisted partial nephrectomy with preoperative superselective embolization (Group A, 70 patients) versus intraoperative ultrasound-guided on-clamp robot-assisted partial nephrectomy without embolization (Group B, 70 patients). We assessed operative time, intraoperative blood loss, complications, length of stay, renal function, need for ancillary procedures and blood transfusions. Results: Mean tumour size was 24 versus 25 mm in Group A versus Group B (p = 0.19). Mean operative time was 86.5 versus 121.8 min (p = 0.02), mean blood loss was 72.8 versus 214.2 mL (p = 0.02), and mean haemoglobin drop on postoperative day 1 was 1.1 versus 2.6 g/dL (p = 0.04) in Group A versus Group B. One-month creatinine, hospital stay and enucleated tumour volume were comparable. Ten postoperative complications occurred in Group A (13.3%) and 11 in Group B (15.3%). Following superselective embolization, no patients required blood transfusions versus two patients in Group B. Postoperative selective renal embolization was needed in one case per group. Conclusions: Preoperative superselective embolization of a renal mass with indocyanine-green before off-clamp robot-assisted partial nephrectomy significantly reduces operative time and intraoperative blood loss compared to on-clamp intraoperative ultrasound-guided robot-assisted partial nephrectomy. A longer follow-up is needed to establish the effect on renal function.

RESUMEN

Introduction: Surgery is the recommended treatment for Bosniak IV renal cysts. We performed a retrospective analysis of Bosniak IV lesions surgically removed to increase evidence on their prognostic meaning. Material and methods: Patients with a Bosniak IV cyst were considered. A contrast-enhanced computed tomography (CT) scan or magnetic resonance imaging (MRI) detected a solid component with contrast enhancement. In no case a percutaneous biopsy was performed. A radical (9, 21.4%) or partial (33, 78.6%) nephrectomy was performed with laparoscopic (14, 33.3%) or robot-assisted (28, 66.7%) approach. Analysis of the final pathology was performed, and recurrence rate was assessed. Results: 42 patients were included. Median lesion size was 54.7 mm (IQR 20.0-81.2). A solid tumour was detected in 40 patients (95.2%), whereas in 2 cases (4.8%) a benign cyst without neoplastic component was diagnosed. Final pathology revealed a low-grade clear cell renal cell carcinoma (ccRCC) in 16 cases (38.0%), a multilocular cystic renal neoplasm of low malignant potential in 6 cases (14.3%), a low-grade papillary RCC (pRCC) type I in 4 cases (9.5%), a clear cell papillary RCC (ccpRCC) in 10 cases (23.8%) and an oncocytoma in 2 cases (4.8%). A high-grade ccRCC was detected in 2 cases (4.8%), whereas no patients had a pRCC type II. In all cases surgical margins were negative. Median follow-up was 24 months and no recurrence occurred. Conclusions: Our results increase evidence on the favourable pathology and good prognosis of Bosniak IV renal cysts, supporting the role of surgery as a definitive treatment and suggesting the need for a low-intensity follow-up.

RESUMEN

BACKGROUND: Vapor Tunnel (VT) technology is the result of a pulse modulation during holmium laser emission which reduces stone retropulsion. We present the outcomes of this tool in the treatment of ureteral stones. METHODS: Two hundred ten patients with a ureteral stone were randomly assigned to holmium laser lithotripsy with (group A) or without (group B) the VT technology. The 35 W LithoEVO laser generator (Quanta System, Samarate, Varese, Italy) was used. We compared operative time, dusting time, delivered energy, retreatment rate due to stone push-up, ureteral lesions, and stone-free rate (SFR) and postoperative strictures at 1 month. We also compared outcomes according to stone position. RESULTS: VT technology was associated with significantly lower mean operative time (25.7 vs. 37.2 min), dusting time (9.7 vs. 15.3 min), delivered energy (7.7 vs. 19.9 KJ). In group B 9 patients (8.5%) were retreated due to stone push-up (P=0.01) for a proximal or middle stone, 6 (5.7%) postoperative strictures occurred (P=0.03) and a higher ureteral lesion rate was observed (7.6% vs 35.2%, P=0.04). 1-month SFR was comparable (93.4% vs. 88.6%, P=0.11). Postoperative complication rate was higher in group B (P=0.05). Without VT technology, ureteral lesions and strictures rates were significantly higher independently from stone position. CONCLUSIONS: The VT technology is associated with significantly lower operative and dusting time independently from stone position, due to a reduced retropulsion, which makes treatment quicker and easier. It also avoids stone push-up especially for proximal and middle stones and reduces ureteral lesions, postoperative complications, and ureteral strictures.

RESUMEN

PURPOSE: To compare endoscopic enucleation of the prostate using a thulium: yttrium-aluminum-garnet (Tm:YAG) laser and a super-pulsed thulium fiber laser set in continuous-wave (CW) mode, and to evaluate whether theoretical advantages of thulium fiber lasers, related to their shorter wavelength, translate into relevant clinical differences. METHODS: In total, 110 patients suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia were randomized to undergo either thulium:YAG laser enucleation of the prostate (ThuLEP) or CW thulium fiber laser enucleation of the prostate (CW-ThuFLEP). Intraoperative and postoperative variables and complications were compared. Micturition improvement was assessed at 3-month follow-up using the International Prostate Symptom Score (IPSS), post-void residual urine (PVR) and maximum flow rate (Qmax). Erectile function was evaluated using the International Index of Erectile Function-5 (IIEF-5). RESULTS: No significant differences between the ThuLEP and CW-ThuFLEP groups were found in terms of operative time (70.69 vs 72.41 min), enucleation time (50.23 vs 53.33 min), enucleated tissue weight (40.2 vs 41.9 g), enucleation efficiency (0.80 vs 0.79 g/min), catheterization time (2.45 vs 2.57 days), hospital stay (2.82 vs 2.95 days) and hemoglobin drop (1.05 vs 1.27 g/dl). At 3-month follow-up, no significant differences were found in IPSS (5.09 vs 5.81), Qmax (26.51 vs 27.13 ml/s), PVR (25.22 vs 23.81 ml) and IIEF-5 (14.01 vs 14.54). CONCLUSION: ThuLEP and CW-ThuFLEP were equivalent in relieving patients from LUTS and improving micturition. Theoretical advantages of the TFL, such as shallower penetration depth and improved vaporization capacity, did not translate into relevant perioperative outcomes or clinical differences.

RESUMEN

BACKGROUND: Two-sided dorsal plus ventral oral graft urethroplasty is a new urethra-sparing technique suggested in tight bulbar strictures which are too severe for a simple one-side grafting. The aim of this study was to evaluate long-term outcomes and the success predictive factors of this technique. METHODS: A descriptive retrospective study was conducted on 216 patients undergoing dorsal plus ventral graft urethroplasty for bulbar strictures between 2002 and 2018 in a single high-volume center by a single surgeon (EP). The primary outcome measure was stricture recurrence at follow-up. Surgical procedure was considered failed when any postoperative instrumentation was needed. Univariable and multivariable logistic regression analysis were performed. RESULTS: Median follow-up was 98 months (IQR: 41-131). Among the 216 patients, 188 (87%) were successful and 28 (13%) were failures. Most of the failures (78.4%) were observed during the first 7 years of follow-up, afterward failures were less frequently recorded. Stricture length <1.5 cm and the absence of previous treatments resulted as independent success predictors (respectively P=0.04, OR=0.55 (0.29-0.99) and P=0.02, OR=0.23 (0.06-0.79). Age and stricture etiology were not significant predictors of surgical outcome. The limitation of our survey is that it is a retrospective single center experience. Multicentric experiences from different centers should be performed. CONCLUSIONS: After long-term follow-up in our wide series, the two-sided dorsal plus ventral oral graft bulbar urethroplasty showed a high success rate. Stricture length <1.5 cm and the absence of previous treatments resulted as independent success predictors.

RESUMEN

(1) Background: Our aim is to describe a new mixed indocyanine-non-adhesive liquid embolic agent (Onyx-18) pre-operative renal embolization technique for assisted-robotic and laparoscopic partial nephrectomy with near-infra-red fluorescence imaging. (2) Methods: Thirteen patients with biopsy-proven renal tumors underwent pre-operative mixed indocyanine-ethylene vinyl alcohol (EVOH) embolization (Green-embo) between June 2021 and August 2022. All pre-operative embolizations were performed with a super selective stop-flow technique using a balloon microcatheter to deliver an indocyanine-EVOH mixture into tertiary order arterial branch feeders and the intra-lesional vascular supply. Efficacy (evaluated as complete embolization, correct tumor mapping on infra-red fluorescence imaging and clamp-off surgery) and safety (evaluated as complication rate and functional outcomes) were primary goals. Clinical and pathological data were also collected. (3) Results: Two male and eleven female patients (mean age 72 years) received pre-operative Green-embo. The median tumor size was 29 mm (range 15-50 mm). Histopathology identified renal cell carcinoma (RCC) in 9 of the 13 (69%) patients, oncocytoma in 3 of the 13 (23%) patients and sarcomatoid RCC in 1 of the 13 (8%) patients. Lesions were equally distributed between polar, meso-renal, endo- and exophytic locations. Complete embolization was achieved in all the procedures. A correct green mapping was identified during all infra-red fluorescence imaging. All patients were discharged on the second day after the surgery. The median blood loss was 145 cc (10-300 cc). No significant differences were observed in serum creatinine levels before and after the embolization procedures. (4) Conclusions: The Green-tattoo technique based on a mixed indocyanine-non-adhesive liquid embolic agent (Onyx-18) is a safe and effective pre-operative embolization technique. The main advantages are the excellent lesion mapping for fluorescence imaging, reduction in surgical time, and definitive, complete and immediate tumor devascularization based on the deep Onyx-18 penetration, leading to a very low intra-operative blood loss.

RESUMEN

PURPOSE: We performed a prospective randomized comparison among Retrograde IntraRenal Surgery (RIRS) and MiniPerc (MP) for stones between 10 and 20 mm to evaluate outcomes with the same laser device: Fiber Dust. METHODS: Patients with a single renal stone between 10 and 20 mm were randomized to RIRS (Group A) versus MP (Group B). Exclusion criteria were age < 18 or > 75, presence of acute infection, coagulation impairments, cardiovascular or pulmonary comorbidities. In both groups, the Fiber Dust laser was used. A CT scan after 3 months was performed. A negative CT scan or asymptomatic patients with stone fragments < 3 mm and a negative urinary culture were the criteria to assess the stone-free status. A statistical analysis was carried out to assess success, complication and retreatment rates and need for auxiliary treatments. RESULTS: Between January 2021 and January 2022, 186 patients were enrolled (90 in Group A and 96 in Group B). Mean stone size was 15.8 mm and 14.9 mm in Group A and B, respectively (p = 0.23). The overall stone-free rate (SFR) was 73.3% for Group A and 84.4% for Group B. A higher SFR was reached for upper calyceal stones in Group A (90.4%) lower calyceal stones in Group B (91.6%). Retreatment rate (p = 0.31) and auxiliary procedure rate (p = 0.18) were comparable. Complication rate was 5.5% and 5.2% for Groups A and B, respectively. CONCLUSIONS: RIRS and MP are both effective to obtain a postoperative SFR with Fiber Dust. According to the stone position one treatment is superior to the other one.

RESUMEN

Pulmonary arterial hypertension (PAH) is a severe complication of connective tissue diseases (CTD). Its early diagnosis is essential to start effective treatment. In the present paper, we aimed to evaluate the role of plasma osteopontin (OPN) as a candidate biomarker of PAH in a cohort of CTD patients. OPN is a pleiotropic protein involved in inflammation and fibrogenesis and, therefore, potentially promising in this specific clinical context. We performed a cross-sectional observational study on a cohort of 113 CTD patients (females N = 101, 89.4%) affected by systemic sclerosis N = 88 (77.9%), mixed connective tissue disease N = 10 (8.8%), overlap syndrome N = 10 (8.8%) or undifferentiated connective tissue disease N = 5 (4.4%). CTD-PAH patients showed significantly higher OPN plasma values than patients with CTD alone (241.0 (188.8-387.2) vs. 200.7 (133.5-281.6) ng/mL; p = 0.03). Although OPN levels were directly correlated with age and inversely with glomerular filtration rate, they remained associated with PAH at multivariate analysis. In conclusion, OPN was significantly associated with PAH among patients with CTD, suggesting it may have a role as a non-invasive disease biomarker of PAH.

RESUMEN

INTRODUCTION: The purpose of the study was to evaluate the feasibility of irradiation after prostatectomy in the presence of asymptomatic pelvic lymphocele. PATIENTS AND METHODS: The inclusion criteria for this study were: (1) patients referred for postoperative (adjuvant or salvage) intensity modulated radiotherapy (IMRT; 66-69 Gy in 30 fractions); (2) detection of postoperative pelvic lymphocele at the simulation computed tomography [CT] scan; (3) no clinical symptoms; and (4) written informed consent. Radiotherapy toxicity and occurrence of symptoms or complications of lymphocele were analyzed. Dosimetric data (IMRT plans) and the modification of lymphocele volume during radiotherapy (cone beam CT [CBCT] scan) were evaluated. RESULTS: Between January 2011 and July 2013, in 30 of 308 patients (10%) treated with radiotherapy after prostatectomy, pelvic lymphocele was detected on the simulation CT. The median lymphocele volume was 47 cm(3) (range, 6-467.3 cm(3)). Lymphocele was not included in planning target volume (PTV) in 8 cases (27%). Maximum dose to lymphocele was 57 Gy (range, 5.7-73.3 Gy). Radiotherapy was well tolerated. In all but 2 patients, lymphoceles remained asymptomatic. Lymphocele drainage-because of symptom occurrence-had to be performed in 2 patients during IMRT and in one patient, 7 weeks after IMRT. CBCT at the end of IMRT showed reduction in lymphocele volume and position compared with the initial data (median reduction of 37%), more pronounced in lymphoceles included in PTV. CONCLUSION: Radiotherapy after prostatectomy in the presence of pelvic asymptomatic lymphocele is feasible with acceptable acute and late toxicity. The volume of lymphoceles decreased during radiotherapy and this phenomenon might require intermediate radiotherapy plan evaluation.

RESUMEN

OBJECTIVE: To describe the first series of robot-assisted laparoscopic radical prostatectomy (RALP) using the ALEXIS™ trocar device when removal of the specimen is necessary for intraoperative frozen-section pathology. MATERIALS AND METHODS: Consecutive RALP using the ALEXIS were prospectively catalogue. Perioperative data, including preoperative oncologic diagnosis, operative time, estimated blood loss (EBL), size of incision for umbilical trocar, complications related to trocar, and length of hospital stay, were analyzed. RESULTS: One hundred twenty-eight patients were analyzed. The mean operative time was 216 minutes, mean time to trocar placement was 4 minutes, and mean EBL was 172 mL. The incision size for a trocar was 2-3 cm in 117 patients and 1 incisional hernia was observed. The mean hospital stay was 3 days and mean follow-up was 4 months. CONCLUSION: The ALEXIS trocar provides an easy and fast intraoperative removal of the specimen for frozen pathology during RALP, even for large prostates. Safe and cosmetic results with a low intraoperative complication rate are acquired with the wound retractor.

RESUMEN

PURPOSE: To describe a new technique for the right template RPLND able to offer a optimal exposure of surgical field, minimal bowel mobilization, and enabling a more "openlike dissection" technique. METHODS: We used a variant of the aortic lymphadenectomy previously described by Magrina et al. for gynecologic malignancies. The patient is placed in a steep Trendelenburg, supine position and the robot column, at the patient's head. The trocar position is specular to that used for RALP and known for generating no collision between the robotic arms. The node dissection of the right template, including laterocaval and interaortocaval nodes, is carried out like in the "open" split-and-roll technique. RESULTS: The docking time was 15', the console time was 192', the blood loss was irrelevant (50 mL), and the number of retrieved nodes was 19. The exposure of the infrarenal vein region of the operatory field resulted optimal without extensive bowel mobilization. The dissection perfectly mimicked the open procedure. CONCLUSIONS: As the left RPLND template includes only para-aortic lymph nodes, the left full flank position seems adequate. On the contrary, it enables a less good exposure of the more extensive right RPLND template, requiring excellent robotic surgical skills to overpass related deadlocks. On the contrary, our technique allows adequate and safe performance of the robotic. It enables a good view of the retroperitoneal space reducing the need of bowel mobilization to obtain a good exposure of the operatory field. Moreover, the patient's supine position makes the procedure more similar to the open technique.

RESUMEN

We report the case of a 66 years old woman with histological diagnosis of muscle-invasive high grade transitional cell carcinoma and clinical diagnosis (TC) of metastatic disease treated with a platinum based combination chemotherapy obtaining a pathologic complete response. Neoadjuvant chemotherapy for bladder cancer even with its limitations regarding patients selection, current development of surgical technique and current chemotherapy combination has shown to improve overall survival by 5-7% at 5 years and should be considered in muscle invasive bladder cancer, irrespective of definitive treatment.

RESUMEN

UNLABELLED: Study Type - Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? The open simple prostatectomy (OSP) is the 'gold standard' for high-volume prostate adenomas. It shows very good functional results despite its invasiveness. Minimally invasive approaches, e.g. laparoscopy or holmium laser enucleation of the prostate, have been 'tested' but none have proved a substitute for the OSP. The robot-assisted approach provides optimal functional results and is easy to perform for experienced robotic surgeons. Extending the indication of robotics to low-incidence pathologies can take advantage of the opportunity to 'see the procedure' using available information technology, e.g. Youtube™ that presents as an unexpectedly useful tool. OBJECTIVE: • To evaluate the outcome, feasibility and reproducibility of a robot-assisted (RA) approach for simple prostatectomy (SP) in cases of high-volume symptomatic benign prostatic hyperplasia (HVS-BPH). PATIENTS AND METHODS: • In all, 35 consecutive patients underwent RASP for HVS-BPH using a previously described technique. • The mean prostate volume on preoperative transrectal ultrasonography was 106.6 mL. • All but two patients (with bladder calculi) had an adenoma volume of >65 mL and 27 (77.1%) >80 mL. Nine patients (25.7%) had an indwelling catheter. • The mean International Prostate Symptom Score (IPSS) was 28. RESULTS: • The median operative duration was 180 min and the mean hospital stay was 3.17 days. • The mean catheter duration was 7.4 days and discontinuous or continuous catheter irrigation was required in two and seven patients, respectively (25.1%). • In all, 10 patients (28.6%) had practically no blood loss. No patients had a transfusion. • The mean postoperative peak urinary flow was 18.9 mL/s (P < 0.001), while the mean IPSS was 7 (P < 0.001). • For costs, while superficially RASP appeared more expensive than open SP (OSP), when considering the higher costs of hospitalisation for OSP, RASP was cheaper. Also, bipolar-TURP costs in patients with large-volume prostates had rather similar costs to RASP. CONCLUSIONS: • RASP is a feasible and reproducible procedure with outcome advantages when compared with the open or with other minimally invasive techniques (laser or laparoscopy). As a result, a RA approach is worth considering in cases of high-volume prostate adenomas. • Extending the indication of the RA approach, to the SP, requires firstly that the surgeon be proficient in RA surgery and secondly that as the incidence rate of HVS-BPH is low, the surgeon has had the opportunity to 'see the procedure'.

RESUMEN

BACKGROUND: Assessing the neuroendocrine (NE) pattern in castration-resistant prostate cancer (CRPC) may prove useful in selecting potential responders to target therapies such as somatostatin analogues. The aim of this study was to define a panel of markers or examinations appropriate to characterize NE differentiation (NED). METHODS: Forty-seven patients with CRPC underwent a systematic diagnostic attempt to characterize the NE phenotype using a plasma blood test for chromogranin A (CgA) and immunohistochemical staining of needle biopsy-obtained specimens (CgA, somatostatin receptor 2 [SSTR2], Ki-67, and androgen receptors). In a subgroup of 26 patients, somatostatin receptor scintigraphy using (111)In-DTPA-d-Phe octreotide (octreotide scintigraphy; Octreoscan, Covidien, Hazelwood, MO) was also performed. RESULTS: NED was found in 85.1% of patients (if serum CgA, tissular CgA, and tissular SSTR2 were considered separately: 54%, 67%, and 58%, respectively). Only 15% of the 26-patient subgroup had an abnormal octreotide scintigraphy result. Although p-CgA and t-CgA were associated with more aggressive disease with a worse prognosis, patients with positive tissular SSTR2 staining had longer overall survival (OS). CONCLUSION: This systematic approach to explore the NED in a quite homogeneous group of patients with CRPC seems reproducible and appropriate. Further investigations are required to validate this panel and better characterize potential responders to targeted therapy.

RESUMEN

OBJECTIVE: To compare the early oncological, perioperative and functional outcomes of robotic-assisted radical prostatectomy (RARP) vs open retropubic RP (RRP) in a laparoscopically naive centre, as robotic assistance aids the laparoscopically naive surgeon in minimally invasive prostate surgery, by offering magnification and superior dexterity. PATIENTS AND METHODS: From 1 November 2006 to 31 December 2007, 120 patients had RARP; this group was followed prospectively and evaluated for early oncological, perioperative and functional outcomes (measured at 3, 6 and 12 months after surgery), and compared to a historical control group of consecutive patients who had RRP from 20 May 2004 to 28 February 2007. All patients were operated by the same laparoscopically naive surgeons. The comparison was by matched-pair analysis. RESULTS: The baseline characteristics of the two groups were equivalent, although there was a higher percentage of patients with pT3/pT4 disease in the RRP group. As a proxy for oncological outcome, positive surgical margins were equivalent in the two groups (22% RARP vs 25% RRP, P = 0.77). The overall mean (range) surgical duration was significantly longer in RARP group, at 215 (165-450) min vs 160 (90-240) min in the RRP group (P < 0.001). However, RARP had a statistically significant advantage over RRP for estimated blood loss, of 200 vs 800 mL (P < 0.001), duration of catheterization (6 vs 7 days P < 0.001) and length of stay (3 vs 6 days, P < 0.001) The 3, 6 and 12-month continence rates were 70%, 93% and 97% vs 63%, 83% and 88% after RARP and RRP, respectively (P = 0.15, 0.011 and 0.014). The 3, 6 and 12 month overall potency recovery rate was 31%, 43% and 61% vs 18%, 31% and 41%, after RARP and RRP, respectively (P = 0.006, 0.045 and 0.003). CONCLUSION: Our initial experience showed the feasibility of RARP in a laparoscopically naive centre. RRP seems to be a faster procedure, whereas RARP provided better results in terms of estimated blood loss, hospitalization and functional results. The early oncological outcome seemed to be equivalent in the two groups.
