ABSTRACT

PURPOSE: To assess the learning curve of Thulium laser enucleation of the prostate (ThuLEP) of a single surgeon. METHODS: Hundred patients suffering from benign prostatic hyperplasia were treated by the same surgeon. In all cases, a well-trained urologist was present in the operating room. Patients urinary function was assessed preoperatively using the International Prostate Symptoms Score (IPSS), maximum flow rate and Post-Void Residual volume. Preoperative prostate volume was recorded. Enucleation and morcellation efficiency and complication rate were evaluated. Patients were divided into 5 cohorts of 20 consecutive cases to assess changes in outcomes through time. RESULTS: Mean age of patients was 73.1 years (SD 17.5) and mean prostate volume was 89.7 ml (SD 55.1). Overall, mean enucleation and morcellation efficiency were 1.7 (SD 2.9) and 5.1 (SD 2.7) g/min. A statistically significant increase in enucleation efficiency was observed when comparing cohort 1 vs 2 (0.9 vs 1.3 g/min, p = 0.03) and cohort 2 vs 3 (1.3 vs 1.7 g/min, p = 0.02). A statistically significant increase in morcellation efficiency was observed when comparing cohort 1 vs 2 (2.8 vs 3.7 g/min, p = 0.02) and cohort 2 vs 3 (3.7 vs 4.9 g/min, p = 0.03). In both cases, no significant differences were observed when comparing the following cohorts. Complication rate showed no significant differences throughout the caseload. CONCLUSIONS: In our single-surgeon experience, we observed a learning curve of nearly 60 cases for the ThuLEP procedure in presence of a well-trained surgeon. Complication rate was low from the beginning of surgical experience.

ABSTRACT

To evaluate the performance of a mathematical model to drive preoperative planning between RIRS and MiniPerc (MP) for the treatment of renal stones between 10 and 20 mm. Patients with a renal stone between 10 and 20 mm were enrolled. A mathematical model named Stone Management According to Size-Hardness (SMASH) score was calculated: hounsfield units (HU) χ stone maximum size (cm)/100. Patients were divided into 4 groups: RIRS with score < 15 (Group A), RIRS with score ≥ 15 (Group B), MP with score < 15 (Group C), MP with score ≥ 15 (Group D). Cyber Ho device was always used. Stone free rate (SFR) was assessed after 3 months. Complication rate and need for auxiliary procedures were evaluated. Between January 2019 and December 2021, 350 patients were enrolled (87, 88, 82 and 93 in Groups A, B, C and D). Mean stone size was 13.1 vs 13.3 mm in Group A vs B (p = 0.18) and 16.2 vs 18.1 mm in Group C vs D (p = 0.12). SFR was 82%, 61%, 75% and 85% for Groups A, B, C and D. SFR was comparable between Groups C and D (p = 0.32) and Groups A and C (p = 0.22). SFR was significantly higher in Group A over B (p = 0.03) and in Group D over B (p = 0.02). Complication rate was 2.2%, 3.4%, 12.1%, 12.9% for Groups A, B, C, D. RIRS and MP are both safe and effective. The mathematical model with the proposed cut-off allowed a proper allocation of patients between endoscopic and percutaneous approaches.Registration number of the study ISRCTN55546280.

ABSTRACT

Introducción El acceso con trocar óptico (ATO) es una técnica modificada de laparoscopia cerrada cuyo objetivo es minimizar el riesgo de lesiones vasculares o intestinales y reducir la posible fuga de gas. Se ha analizado el efecto de la curva de aprendizaje (CA) para el ATO, considerando n=30 procedimientos como umbral para definir un nivel aceptable de experticia. Nuestro objetivo es evaluar el impacto de la CA en los primeros 30 casos de ATO realizados por un aprendiz. Métodos Se trata de un estudio prospectivo aleatorizado en 60 pacientes planificadas para cirugía ginecológica laparoscópica. Las pacientes fueron seleccionadas aleatoriamente para el ATO realizado por un cirujano sin entrenamiento previo en la técnica o por un cirujano experto. La CA se evaluó mediante: 1) tiempo hasta lograr el acceso; 2) número de correcciones hechas por el experto; 3) número de veces en que la punta del trocar se detuvo en la capa preperitoneal; 4) errores al realizar la incisión en la piel; 5) veces en que la punta del trocar termina bajo el epiplón; 6) complicaciones. Para analizar el CA en los 30 primeros casos, se estratificaron los procedimientos en 3 grupos (casos 1-10; 11-20; 21-30) tanto para el aprendiz como para el experto y se compararon las variables de la CA. Resultados De forma global, el tiempo medio de inserción para el ATO fue de 56s. No se registraron complicaciones intraoperatorias ni postoperatorias graves. El tiempo medio de inserción fue estadísticamente más largo para el aprendiz en comparación con el experto en los 10 primeros casos (91s frente a 33s, respectivamente, p=0,01). En los casos 11-20 y 21-30, la ventaja de tiempo del cirujano experto se hizo menos evidente (p=0,05). El número de veces que la punta del trocar se detuvo en la capa preperitoneal fue similar entre los grupos, así como las veces que la punta del trocar llegó por debajo del epiplón. Conclusiones La técnica de ATO es rápida y reproducible . ... (AU)


Introduction The optical trocar access (OTA) is a modified closed technique that aims to minimize the risk of vascular or bowel injuries while reducing the likelihood of gas leakage. A learning curve (LC) effect for OTA has been invoked with n=30 procedures being considered as a threshold to define expertise. We aim to evaluate the impact of the LC within the first thirty cases of OTA performed by a trainee. Methods This is a prospective randomized study on 60 patients elected to laparoscopic gynecological surgery. Patients were randomized to have OTA insertion by a junior surgeon or by an expert. LC was evaluated by: 1) insertion time; number of: 2) corrections by the senior; 3) times the tip of the trocar stopped in the preperitoneal layer; 4) mistakes of skin incision; 5) times the tip of the trocar ends under the omentum; 6) complications. To analyze the LC within the first 30 cases, procedures were stratified in 3 groups (cases 1-10; 11-20; 21-30) for both trainee and expert and LC variables were compared. Results Overall, mean OTA insertion time was 56s. No major intra- and post-operative complications were recorded. Mean insertion time was statistically significantly longer for the trainee compared to the expert within the first 10 cases (91 vs 33s respectively, p=0.01). For cases 11-20 and 21-30, time advantage of the senior surgeon is less evident (p=0.05). The number of times the tip of the trocar stopped in the preperitoneal layer was similar between groups, as well as times the tip of the trocar ends under the omentum. Conclusions OTA is a fast and simple way to achieve the pneumoperitoneum and first trocar insertion as a single step. The current series confirms the effectiveness of the technique since the beginning of the LC. (AU)

ABSTRACT

INTRODUCTION: The optical trocar access (OTA) is a modified closed technique that aims to minimize the risk of vascular or bowel injuries while reducing the likelihood of gas leakage. A learning curve (LC) effect for OTA has been invoked with n = 30 procedures being considered as a threshold to define expertise. We aim to evaluate the impact of the LC within the first thirty cases of OTA performed by a trainee. METHODS: This is a prospective randomized study on 60 patients elected to laparoscopic gynecological surgery. Patients were randomized to have OTA insertion by a junior surgeon or by an expert. LC was evaluated by: 1) insertion time; number of: 2) corrections by the senior; 3) times the tip of the trocar stopped in the preperitoneal layer; 4) mistakes of skin incision; 5) times the tip of the trocar ends under the omentum; 6) complications. To analyze the LC within the first 30 cases, procedures were stratified in 3 groups (cases 1-10; 11-20; 21-30) for both trainee and expert and LC variables were compared. RESULTS: Overall, mean OTA insertion time was 56 s. No major intra- and post-operative complications were recorded. Mean insertion time was statistically significantly longer for the trainee compared to the expert within the first 10 cases (91 vs 33 s respectively, P = .01). For cases 11-20 and 21-30, time advantage of the senior surgeon is less evident (P = .05). The number of times the tip of the trocar stopped in the preperitoneal layer was similar between groups, as well as times the tip of the trocar ends under the omentum. CONCLUSIONS: OTA is a fast and simple way to achieve the pneumoperitoneum and first trocar insertion as a single step. The current series confirms the effectiveness of the technique since the beginning of the LC.

ABSTRACT

OBJECTIVE: To compare intra and early postoperative outcomes between pulsed-wave and continuous-wave Thulium Fiber Laser Enucleation of the Prostate (PW-ThuFLEP vs CW-ThuFLEP) for the treatment of benign prostatic hyperplasia. METHODS: 238 patients with lower urinary tract symptoms due to benign prostatic hyperplasia underwent PW-ThuFLEP (118 patients) vs CW-ThuFLEP (120 patients). Preoperative prostate volume, adenoma volume, prostate-specific antigen (PSA), and hemoglobin values were recorded. International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual volume, and International Index of Erectile Function-5 score (IIEF-5) were assessed. Operative time, enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin drop, and postoperative complications were recorded. Micturition improvements and sexual outcomes were evaluated 3months after surgery. RESULTS: CW-ThuFLEP showed shorter operative time (61.5 vs 67.4 minutes, P = .04). Enucleation time (50.2 vs 53.3 minutes, P = .12), enucleation efficiency (0.8 vs 0.7 g/min, P = .38), catheterization time (2.2 vs 2.1days, P = .29), irrigation volume (32.9 vs 32.8L, P = .71), hospital stay (2.8 vs 2.6days, P = .29) and hemoglobin drop (0.38 vs 0.39 g/dL, P = .53) were comparable. No significant difference in complication rate was observed. At 3-month follow-up, the procedures did not show any significant difference in IPSS, Qmax, post-void residual volume, IIEF-5, and PSA value. CONCLUSION: PW-ThuFLEP and CW-ThuFLEP both relieve lower urinary tract symptoms equally, with high efficacy and safety. Operative time was significantly shorter with CW-ThuFLEP, but with a small difference with low clinical impact. Enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin and PSA drop, complication rate, and sexual outcomes showed no differences.

ABSTRACT

The occurrence of asymptomatic bacteriuria concomitant to urolithiasis is an issue for patients undergoing renal stone treatment. Disposing of a preoperative urine culture is essential to reduce the risk of septic events. The endpoint of the study is to report which characteristics of candidates for renal stone treatment are frequently associated with positive urine culture. 2605 patients were retrospectively enrolled from 14 centers; inclusion criteria were age > 18 and presence of a single renal stone 1-2 cm in size. The variables collected included age, gender, previous renal surgery, comorbidities, skin-to-stone distance, stone size, location, density, presence of hydronephrosis. After a descriptive analysis, the association between continuous and categorical variables and the presence of positive urine culture was assessed using a logistic regression model. Overall, 240/2605 patients (9%) had preoperative bacteriuria. Positive urine culture was more frequent in females, patients with previous renal interventions, chronic kidney disease, congenital anomalies, larger stones, increased density. Multivariate analysis demonstrated that previous renal interventions (OR 2.6; 95% CI 1.9-3.4; p < 0.001), renal-related comorbidities (OR 1.31; 95% CI 1.19-1.4; p < 0.001), higher stone size (OR 1.06; 95% CI 1.02-1.1; p = 0.01) and density (OR 1.00; 95% CI 1.0-1.00; p = 0.02) were associated with bacteriuria; male gender and lower caliceal location were inversely related to it. Beyond expected risk factors, such as female gender, other parameters are seemingly favoring the presence of positive urine culture. The awareness of variables associated with bacteriuria allows to assess which individuals are at increased risk of presenting bacteriuria and reduce the rate of septic complications.

ABSTRACT

OBJECTIVE: To compare intraoperative ureteral injuries in RIRS with UAS insertion with the rate of postoperative infections after RIRS without UAS insertion. PATIENTS AND METHODS: In this randomized trial, patients who received an indication for RIRS between January 2017 and December 2017 were divided into two groups. Group A had no UAS insertion and Group B had UAS insertion. Post-Ureteroscopic Lesion Scale (PULS) grading was performed after UAS or flexible ureteroscope removal. Proximal, middle and distal ureteral lesions were evaluated and compared according to the PULS scale. Additionally, patients in both groups were followed postoperatively to assess any infective complication. RESULTS: The evaluation comprised 181 patients, 89 for group A and 92 for group B. Overall stone-free rate, clinically insignificant residual fragments, and final stone-free rate were 41.4%, 53.5%, and 95%, respectively. There were 33 (37.1%) patients with ureteral lesions in group A while 42 (45.6%) patients had ureteral lesions in group B, with no significant difference. On the other hand, the overall presence of postoperative infection rate was much higher for Group A (37.1% vs 16.3% P = 0.03). CONCLUSIONS: UAS insertion does not result in a higher number of ureteral injuries. UAS insertion during RIRS allows a lower rate of postoperative infections. CLINICAL TRIAL REGISTRATION NUMBER (ISRCTN REGISTRY NUMBER): 55546280.

ABSTRACT

INTRODUCTION: Robotic technology has gained popularity allowing performance of several complex and difficult reconstructive procedures. This video demonstrates the advantages of the robotic approach for a "keel" bladder neck construction in an obese patient. MATERIAL AND METHODS: A 13 year-old-girl (BMI = 28) already treated elsewhere for a uro-genital sinus (Total Urogenital Mobilization) has been evaluated for disturbing persistent total urinary incontinence. Cisto-colposcopy revealed an extremely short and tortuous urethra. Bladder neck was wide open and incompetent. Video-Urodynamic evaluation showed a bladder with a capacity of 280 mL with low voiding pressures (14-16 cmH20) and continuous urinary leakage. MAG3 scan confirmed normal renal function. Thus, the girl underwent a laparoscopic robotic-assisted "keel" bladder neck construction. RESULTS: The patient was discharged on 5th post-operative day without complications. After 4 years she is voiding spontaneously (300 cc) without post-void residuals. She has presented a persistent mild stress incontinence successfully treated with subsequent endoscopic bulking agent injection. CONCLUSIONS: Robotic access to the bladder neck region is an excellent option with ideal anatomical exposure compared to conventional open surgery, especially in obese patients. The "keel" procedure allows to reconfigure and tubularize a wide and incompetent bladder neck creating a continent funnel without the absolute need of concomitant ureteric reimplantation.

ABSTRACT

PURPOSE: Live surgery (LS) is considered a useful teaching opportunity. The benefits must be balanced with patient safety concerns. To evaluate the rate of complications of a series of urologic LS performed by experts during the Congress Challenge in Laparoscopy and Robotics (CILR). METHODS: We present a large, multi-institution, multi-surgeon database that derives from 12 CILR events, from 2004 to 2015 with a total of 224 cases. Radical prostatectomy (RP) was the most common procedure and a selection of complex cases was noted. The primary measure was postoperative complications and use of a Postoperative Morbidity Index (PMI) to allow quantitative weighing of postoperative complications. RESULTS: From 12 events, the number of cases increased from 11 in 2004 to 27 in 2015 and a total of 27 surgeons. Of 224 cases (164 laparoscopic and 60 robotic), there were 26 (11.6%) complications: 5 grade I, 5 grade II, 3 grade IIIa, 12 grade IIIb and 1 grade V, the latter from laparoscopic cystectomy. Analysis of PMI was 23 times higher from cystectomy compared to RP. CONCLUSIONS: In the setting of live surgery, the overall rate of complications is low considering the complexity of surgeries. The PMI is not higher in more complex procedures, whereas RP seems very safe.

ABSTRACT

INTRODUCTION: Minimally invasive pyeloplasty (MIP) for ureteropelvic junction (UPJ) obstruction in children has gained popularity over the past decade as an alternative to open surgery. The present study aimed to identify the factors affecting complication rates of MIP in children, and to compare the outcomes of laparoscopic (LP) and robotic-assisted laparoscopic pyeloplasty (RALP). MATERIALS AND METHODS: The perioperative data of 783 pediatric patients (<18 years old) from 15 academic centers who underwent either LP or RALP with an Anderson Hynes dismembered pyeloplasty technique were retrospectively evaluated. Redo cases and patients with anatomic renal abnormalities were excluded. Demographics and operative data, including procedural factors, were collected. Complications were classified according to the Satava and modified Clavien systems. Failure was defined as any of the following: obstructive parameters on diuretic renal scintigraphy, decline in renal function, progressive hydronephrosis, or symptom relapse. Univariate and multivariate analysis were applied to identify factors affecting the complication rates. All parameters were compared between LP and RALP. RESULTS: A total of 575 children met the inclusion criteria. Laparoscopy, increased operative time, prolonged hospital stay, ureteral stenting technique, and time required for stenting were factors influencing complication rates on univariate analysis. None of those factors remained significant on multivariate analysis. Mean follow-up was 12.8 ± 9.8 months for RALP and 45.2 ± 33.8 months for LP (P = 0.001). Hospital stay and time for stenting were shorter for robotic pyeloplasty (P < 0.05 for both). Success rates were similar between RALP and LP (99.5% vs 97.3%, P = 0.11). The intraoperative complication rate was comparable between RALP and LP (3.8% vs 7.4%, P = 0.06). However, the postoperative complication rate was significantly higher in the LP group (3.2% for RALP and 7.7% for LP, P = 0.02). All complications were of no greater severity than Satava Grade IIa and Clavien Grade IIIb. DISCUSSION: This was the largest multicenter series of LP and RALP in the pediatric population. Limitations of the study included the retrospective design and lack of surgical experience as a confounder. CONCLUSIONS: Both minimally invasive approaches that were studied were safe and highly effective in treating UPJ obstruction in children in many centers globally. However, shorter hospitalization time and lower postoperative complication rates with RALP were noted. The aims of the study were met.

ABSTRACT

BACKGROUND: Since there is still an unmet need for potent adjuvant strategies for renal cancer patients with high progression risk after surgery, several targeted therapies are currently evaluated in this setting. We analyzed whether inclusion criteria of contemporary trials (ARISER, ASSURE, SORCE, EVEREST, PROTECT, S-TRAC, ATLAS) correctly identify high-risk patients. METHODS: The study group comprised 8873 patients of the international CORONA-database after surgery for non-metastatic renal cancer without any adjuvant treatment. Patients were divided into potentially eligible high-risk and assumable low-risk patients who didn't meet inclusion criteria of contemporary adjuvant clinical trials. The ability of various inclusion criteria for disease-free survival (DFS) prediction was evaluated by Harrell's c-index. RESULTS: During a median follow-up of 53 months 15.2% of patients experienced recurrence (5-year-DFS 84%). By application of trial inclusion criteria, 24% (S-TRAC) to 47% (SORCE) of patients would have been eligible for enrollment. Actual recurrence rates of eligible patients ranged between 29% (SORCE) and 37% (S-TRAC) opposed to <10% in excluded patients. Highest Hazard Ratio for selection criteria was proven for the SORCE-trial (HR 6.42; p < 0.001), while ASSURE and EVEREST reached the highest c-index for DFS prediction (both 0.73). In a separate multivariate Cox-model, two risk-groups were identified with a maximum difference in 5-year-DFS (94% vs. 61%). CONCLUSION: Results of contemporary adjuvant clinical trials will not be comparable as inclusion criteria differ significantly. Risk assessment according to our model might improve patient selection in clinical trials by defining a high-risk group (28% of all patients) with a 5-year-recurrence rate of almost 40%.

ABSTRACT

BACKGROUND: To report the perioperative, functional and oncological outcomes of salvage robot-assisted laparoscopic prostatectomy (s-RARP) in a propensity score-matched analysis. STUDY DESIGN: 53 patients underwent s-RARP at our institution. Perioperative, functional and oncological outcomes were compared between propensity matched cohorts. RESULTS: Patients in the s-RARP group were at significantly higher risk based on the D'Amico classification system (p = 0.010). Estimated blood loss, complication rate, hospital stay, BCR risk, persistent cancer and time to return of potency were similar between groups (full nerve spare [NS] n = 22). In the s-RARP cohort there was a higher prevalence of lymphovascular invasion (26.4% versus 13.2%; p = 0.032), time to catheter removal and a higher prevalence of anastomotic leaks in the postoperative period (34.0% vs 5.7%, p < 0.010). The hazard ratio for return to potency regardless of nerve sparing in the s-RARP group was 0.47 (95% CI 0.25-0.88). Significantly more patients undergoing primary RARP with partial nerve sparing (NS) recovered continence (p < 0.001) and potency (p = 0.043) compared to partial NS s-RARP patients. The return to continence and potency did not differ between full NS cases (n = 22; p = 0.616). CONCLUSIONS: Salvage RARP patients undergoing surgery have more high risk disease. Patients should be counseled that they are more likely to demonstrate anastomotic leakage on cystogram, and prolonged catheterization times. The time to potency and continence in s-RARP undergoing partial and no NS was significantly delayed (n = 49). The proportion of patients returning to potency and continence was also lower in our s-RARP group.

ABSTRACT

Robot assisted radical prostatectomy (RARP) represents the leading application of robotic surgery in the urologic field and it has become the main treatment option for localized prostate cancer (PCa) in the USA In the present review we summarized and critically analyzed the literature of the past five years about this widely used robotic procedure. RARP has continuously evolved in terms of technical modifications and procedural steps. Long-term data are now available, suggesting comparable oncological outcomes to those of open and laparoscopic radical prostatectomy. Good functional outcomes have also been demonstrated. Technological innovations and the introduction of more advanced robotic platforms featuring novel arm-integrated equipment, together with a mature clinical experience with the robotic approach, are likely to lead towards optimal outcomes. Despite the expanding clinical implementation of RARP in the management of prostate cancer, some issues related to this procedure remain matter of debate, such as costs, comparative outcomes versus other approaches, and its role in high risk disease.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Our goal was to evaluate the perioperative, functional and intermediate term oncological outcomes of robot assisted radical prostatectomy (RARP) in patients ≥ 70 years. MATERIALS AND METHODS: The study population (N = 3241) consisted of consecutive patients who underwent RARP for localized prostate cancer by a single surgeon (VP) from January 2008 through February 2012. A query of our Institutional Review Board approved registry identified 400 men ≥ 70 years of age, with good functional status (Charlson co-morbidity index < 3). These patients were propensity score matched to younger patients. Perioperative and postoperative functional and oncologic outcomes for the two groups were compared. RESULTS: Full nerve sparing as well as the ease of nerve sparing were similar in 2 groups. Intra-operative complications were comparable. Postoperative complication occurrence rates were similar. At mean follow up of 34.1 months and 37.2 months respectively in younger and older patients, the continence rate was comparable in 2 groups (91.3% and 87.3%).Average time to continence and potency were similar in 2 groups. A greater proportion of younger patients became potent than elderly (52.3% vs 33.5%,p < 0.001).The biochemical recurrence (BCR) rate was comparable in 2 groups (7.8% vs 8.3%; p = 0.79). The mean time to BCR was also comparable in 2 groups (16 months vs 22.6 months; p = 0.07). CONCLUSIONS: In appropriately selected patients (minimal comorbidities with CCI ≤ 2, life expectancy >10 years, localized prostate cancer) RARP is a reasonable option in patients ≥ 7 0 years and provides comparable perioperative, functional and intermediate term oncologic outcomes as compared to younger patients.

ABSTRACT

OBJECTIVES: To compare the concordance of prostate cancer (PCa) laterality between the extended transperineal (TP) or transrectal (TR) prostate biopsy (BP) and radical prostatectomy (RP) specimens. To identify predictors of laterality agreement between BP and RP. MATERIALS AND METHODS: Data from 533 consecutive patients with PCa (278 TP and 255 TR-diagnosed) treated with RP were analyzed. A 12-core technique was used for both TP and TR biopsies. Additional cores were obtained when necessary. RESULTS: Overall, the percentage of agreement of PCa laterality between BP and RP was 60% (K = 0.27, p < 0.001). However, the RP confirmation of unilaterality at BP was obtained in just 33% of the cases. Considering the concordance on bilaterality as the ″target″ of our analysis, the sensitivity and specificity were 54.3% and 98.2% , respectively, with TP and 47.5% and 92.5%, respectively with TR. Focusing on patients with unilaterality at biopsy, none of the evaluated preoperative variables (biopsy technique, age, total positive biopsy cores, PSA, prostate volume, Gleason score on biopsy) were able to predict RP bilaterality in the multivariate analyses. CONCLUSIONS: Most of the patients with unilateral involvement at BP harbored bilateral PCa after RP. TR and TP biopsy showed no difference in their capacity to predict the concordance of tumor laterality at RP. None of the preoperative evaluated variables can predict the tumor laterality at RP. Using BP unilaterality to include patients in focal therapy (FT) protocols may hinder the oncologic efficacy of FT.
