RESUMO
This study aimed to analyze perioperative results in robot-assisted laparoscopic urological surgeries, comparing the AirSeal system with traditional pneumoperitoneum systems. This study adhered to the PRISMA guidelines for conducting systematic reviews and meta-analyses. Extensive searches were conducted in PubMed, EMBASE, and Google Scholar, including randomized controlled trials (RCTs) and cohort studies up to June 15, 2024. A combined examination of the studies found that the AirSeal system had superior results in terms of surgery duration, end-tidal carbon dioxide levels, and tidal volume compared to the traditional pneumoperitoneum system. During robotic-assisted partial nephrectomy, the AirSeal team experienced a notable decrease in surgical time, ETCO2, and VT. In addition, the occurrence of SCE was lower in the AirSeal group. However, there were no significant differences observed between the groups regarding EBL, LOHS, overall complications, and major complications. Compared to conventional pneumoperitoneum systems, the AirSeal system offers several advantages in robot-assisted laparoscopic urological surgery: reduced operative time, lower end-tidal CO2 pressure, and decreased tidal volume. Furthermore, implementing the AirSeal system does not lead to higher rates of complications, estimated blood loss, or lengthier hospital stays.

Robot-assisted surgery (RAS) has been integrated into clinical practice to overcome several limitations of conventional open or laparoscopic surgery. After the expiration of the long key patent period of Intuitive Surgical, various robotic systems (RSs) have been developed aiming at improving certain characteristics of the first robotic platform, the Da Vinci RS. This narrative review provides an overview of the current RSs used in urology along with the initial results from their application in urologic procedures. Nine robotic platforms are being analyzed regarding their unique characteristics as well as their efficacy, safety, feasibility, and outcomes in urologic, oncological, or non-oncological operations. The main barrier to the wide application of RAS has been the increased cost that refers to both acquisition and maintenance costs. Besides, the health inequality resulting from the lack of expert robotic surgeons and the difficulty of performing robot-assisted procedures in provincial hospitals should be overcome. However, large properly designed comparative studies are required to establish the role of newly introduced RSs. In addition, urologists should keep abreast of new developments and research in robot-assisted urologic procedures.

BACKGROUND: Surgical interventions are more effective than nonsurgical approaches in providing a cure for stress urinary incontinence (SUI). In this study, we aimed to assess the benefits of tension-free vaginal tape (TVT) abbrevo by comparing its efficacy and complications to those of TVT obturator. METHODS AND RESULTS: 49 and 47 patients at The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University between January 2013 and December 2016 were included in the TVT-O and TVT-A groups, respectively. We evaluate the success rate and perioperative complications associated with TVT-O and TVT-A. A questionnaire that utilized the Patient Global Impression of Improvement (PGI-I) Scale was employed to assess the impact of surgery. Patients were followed up at 1 year, and 5 years after surgery. There were no statistically significant differences found in the efficacy of the TVT-A group and TVT-O group during both the one-year (p = 0.4) and five-year (p = 0.32) follow-up periods. In the period of one-year follow-up, 95.9% (n = 47) of patients in the TVT-O group and 95.8% (n = 45) of patients in the TVT-A group demonstrated improvement. During the period of five-year follow-up, 87.8% (n = 43) of patients in the TVT-O group and 93.6% (n = 44) of patients in the TVT-A group demonstrated improvement. CONCLUSIONS: Based on our findings, TVT-A and TVT-O procedures exhibited similarly high success rates and low frequencies of complications.

In the field of urology, robotic surgery has gained rapid and wide acceptance as a standard surgical approach in the majority of major surgeries over the last decade. To date, the da Vinci surgical system has been the dominant platform in robotic surgery; however, several newly developed robotic systems have recently been introduced in routine clinical practice. Of these, hinotori, the first made-in-Japan robotic system, is characterized by various unique and attractive features different from the existing system, and the use of this system has gradually increased mainly in urologic cancer surgeries, including radical prostatectomy, partial nephrectomy, radical nephrectomy, and radical nephroureterectomy. This review initially describes detailed characteristics of hinotori, then summarizes the early experience with urologic cancer surgeries using hinotori at our institution, and finally discusses the future prospects of robotic surgery using hinotori, considering problems associated with the use of this robotic system.

Introduction: Robotic surgery using da Vinci surgical system has gained prominence in urology; emerging robotic platforms are expanding its applications and increasing affordability. We assess the feasibility and safety of a novel system, the Toumai® robotic system in various urological surgeries. Methods: This prospective study was conducted at the first affiliated hospital of Zhengzhou university. Twenty consecutive patients underwent renal and prostatic surgery with the Toumai. The study assessed technical feasibility (conversion rate) and safety (perioperative complications) of the procedures as primary outcomes. Secondary endpoints included key surgical perioperative outcomes: functional and oncologic results. The Endoscopic Surgical System operates within a master-slave protocol, comprising a Surgeon Console, Patient Platform, and Vision Platform. Results: Seventeen patients underwent various nephrectomy procedures and three underwent radical prostatectomy (RP). There was no conversion to alternative surgical approach; a single (Clavien-Dindo grade ≥3b) complication occurred, and no readmission was recorded within 30 days. The median operative time was 120, 140, and 210 minutes for partial nephrectomy (PN), radical nephrectomy, and RP, respectively. Off-clamp PN was performed in one case, and the warm ischemia time in the remaining two case was 18 minutes. The median docking time was 22 minutes for nephrectomy and 20 minutes for RP; no major robotic malfunction was encountered. At 3-month follow-up, no tumor recurrence was recorded, renal function was well preserved, and the continence status was satisfactory. Conclusions: We present the initial clinical utilization of an innovative robotic platform. Complex urological surgeries were successfully completed without conversions and with minimal complications. Further investigations are warranted to confirm these initial findings.

ABSTRACT Objective: Pyeloplasty is considered the gold standard treatment for ureteropelvic junction obstruction (UPJO). However, the failure rate of pyeloplasty is as high as 10% and repeat pyeloplasty is more difficult. This study aimed to evaluate the efficacy of balloon dilatation for failed pyeloplasty in children. Materials and Methods: Between 2011 and 2017, 15 patients, aged 6 months to 14 years, were treated with balloon dilation for restenosis of UPJO after a failed pyeloplasty. Ultrasound and intravenous urography were used to evaluate the primary outcome. Success was defined as the relief of symptoms and improvement of hydronephrosis, which was identified by ultrasound at the last follow-up. Results: All patients successfully completed the operation, 13 patients by retrograde approach and 2 patients by antegrade approach. Thirteen patients were followed for a median of 15 (4 to 57) months and 2 patients were lost to follow-up. Resolution of the hydronephrosis was observed in 5 cases. The anteroposterior diameter (APD) of the pelvis decreased by an average of 12.4 ± 14.4mm. Eight patients needed another surgery. The average postoperative hospital stay was 1.78 ± 1.4 days. Two patients experienced fever after balloon dilation. No other complications were found. Conclusions: Balloon dilatation surgery is safe for children, but it is not recommended for failed pyeloplasty in that group of patients, owing to the low success rate.

ABSTRACT Introduction: Double-J stent insertion during laparoscopic pyeloplasty is a difficult and time-consuming process and several techniques were defined to perform a double-J stent with an antegrade approach. In this study we present the technique (PICA) of antegrade double-J placement during laparoscopic pyeloplasty by using 14 gauge intravenous cannula. Surgıcal technıque: After we complete the suturing of the posterior wall of the anastomosis during laparoscopic pyeloplasty, we first puncture the abdominal wall with a 14-gauge "intravenous cannula" from a location that provides most suitable angle for inserting the double-J stent into the ureter. We remove the metal needle of the cannula, and the sheath which has an inner diameter of 5.2F remains over the abdominal wall. The double J stent is then advanced from inside the cannula sheath to the intraperitoneal area; under laparoscopic imaging the stent is gently grasped at its distal end using an atraumatic laparoscopic forceps to insert it into the ureter. The stent is then pulled down to its proximal end, and after the guidewire is removed, the proximal end of the double-J stent is placed inside the renal pelvis with an atraumatic forceps. With this technique we can apply the double-J stent in just one step. Additionaly we can use a 14-gauge IV cannula sheath as a trocar when needed during laparoscopic pyeloplasty to retract an organ or reveal an anastomosis line. Comments: Our new technique of antegrade double-J placement during laparoscopic pyeloplasty by 14 gauge intravenous cannula sheath, is very easy and quick to perform.

ABSTRACT Synthetic suburethral slings have become the most widely used technique for the surgical treatment of stress urinary incontinence. Despite its high success rates, significant complications have been reported including bleeding, urethral or bladder injury, urethral or bladder mesh erosion, intestinal perforation, vaginal extrusion of mesh, urinary tract infection, pain, urinary urgency and bladder outlet obstruction. Recent warnings from important regulatory agencies worldwide concerning safety issues of the use of mesh for urogynecological reconstruction have had a strong impact on patients as well as surgeons and manufacturers. In this paper, we reviewed the literature regarding surgical morbidity associated with synthetic suburethral slings.

ABSTRACT Purpose To determine whether using different intraperitoneal insufflation pressures for transperitoneal laparoscopic urologic surgeries decreases postoperative pain. Materials and Methods 76 patients who underwent transperitoneal laparoscopic upper urinary tract surgery at different insufflation pressures were allocated into the following groups: 10mmHg (group I, n=24), 12mmHg (group II, n=25) and 14mmHg (group III, n=27). These patients were compared according to age, gender, body mass index (BMI), type and duration of surgery, intraoperative bleeding volume, postoperative pain score and length of hospital stay. A visual analog scale (VAS) was used for postoperative pain. Results Demographic characteristics, mean age, gender, BMI and type of surgeries were statistically similar among the groups. The mean operation time was higher in group I than group II and group III but this was not statistically significant (P=0.810). The mean intraoperative bleeding volume was significantly higher in group I compared with group II and group III (P=0.030 and P=0.006). The mean length of postoperative hospital stays was statistically similar among the groups (P=0.849). The mean VAS score at 6h was significantly reduced in group I compared with group III (P=0.011). At 12h, the mean VAS score was significantly reduced in group I compared with group II and group III (P=0.009 and P<0.001). There was no significant difference in the mean VAS scores at 24h among three groups (P=0.920). Conclusion Lower insufflation pressures are associated with lower postoperative pain scores in the early postoperative period.

ABSTRACT Purpose: To describe our experience utilizing Laparoendoscopic single site (LESS) surgery in pediatric urology. Materials and Methods: Retrospective chart review was performed on LESS urologic procedures from November 2009 through March 2013. A total of 44 patients underwent 54 procedures including: nephrectomy (23), orchiopexy (14), varicocelectomy (9), orchiectomy (2), urachal cyst excision (3), and antegrade continence enema (3) (ACE). Results: Median patient age was 6.9 years old. Estimated blood loss (EBL), ranged from less than 5cc to 47cc for a bilateral nephrectomy. Operative time varied from 56 mins for varicocelectomy to a median of 360 minutes for a bilateral nephroureterectomy. Incision length ranged between 2 and 2.5cm. In our initial experience we used a commercial port. However, as we progressed, we were able to perform the majority of our procedures via adjacent fascial punctures for instrumentation at the single incision site. One patient did require conversion to an open procedure as a result of bleeding. Three complications were noted (6.8%), with two Clavien Grade 3b complications. Two patients required additional procedures at 1-year follow-up. Conclusions: The use of LESS applies to many pediatric urologic procedures, ideally for ablative procedures or simple reconstructive efforts. The use of adjacent fascial puncture sites for instrumentation can obviate the need for a commercial port or multiple trocars.

O checklist de cirurgia segura da Organização Mundial da Saúde é uma ferramenta útil para diminuir eventos adversos em hospitais, porém sua implantação efetiva ainda é um desafio. Este estudo objetiva avaliar a adesão ao checklist em cirurgias urológicas e ginecológicas de dois hospitais de ensino em Natal, Rio Grande do Norte, Brasil. O desenho foi observacional transversal; selecionaram-se cirurgias eletivas, e a coleta se deu por meio de revisão de prontuários. Descreveu-se a adesão mediante a existência e qualidade do preenchimento do checklist, e analisou-se a associação de fatores estruturais e socioprofissionais valendo-se de análise de regressão múltipla. Das 375 cirurgias revisadas, 61% tinham checklist, e 4% estavam totalmente preenchidos. A existência do checklist se associou às cirurgias ginecológicas (maternidade) (OR = 130,18) e à maior duração da cirurgia (OR = 2,13), enquanto a qualidade do preenchimento se relacionou com as cirurgias urológicas (hospital geral) (β = 26,36). A adesão ao checklist precisa ser aprimorada, e as diferenças sugerem a influência das distintas estratégias de implantação utilizadas em cada instituição.
The WHO surgical safety checklist is a useful tool for decreasing the number of adverse events in hospitals, but its implementation is still a challenge. This study aimed to assess adherence to the checklist in urological and gynecological surgeries at two teaching hospitals in Natal, Rio Grande do Norte, Brazil. A cross-sectional observational design was used, elective surgeries were selected, and data were collected from medical charts. Adherence was based on the quality and proper completion of the checklist, and the association of structural and socio-professional factors was analyzed using multiple regression. Of the 375 surgeries reviewed, 61% included a checklist and 4% were correctly filled out. The existence of a checklist was associated with gynecological surgeries (OR = 130.18) and longer operating time (OR = 2.13), while quality of the checklist was related to urological surgeries (β = 26.36). Adherence to the checklist needs to be improved, and the observed differences suggest the influence of distinct implementation strategies at the two institutions.

INTRODUCTION: We present the initial experience of a novel surgical chair for laparoscopic pelvic surgery, the ETHOS TM (Bridge City Surgical, Portland, OR). MATERIALS AND METHODS: The ETHOS chair has an adjustable saddle height that ranges from 0.89 to 1.22 m high, an overall width of 0.89 m, and a depth of 0.97 m. The open straddle is 0.53 m and fits most OR tables. We performed 7 pelvic laparoscopy cases with the 1st generation ETHOS TM platform including 2 laparoscopic ureteral reimplantations, 5 laparoscopic pelvic lymphadenectomies for staging prostate cancer in which one case involved a laparoscopic radical retropubic prostatectomy, performed by 2 different surgeons. RESULTS: All 7 pelvic laparoscopic procedures were successful with the ETHOS TM chair. No conversion to open surgery was necessary. Survey done by surgeons after the procedures revealed minimal stress on back or upper extremities by the surgeons from these operations even when surgery was longer than 120 minutes. Conversely, the surgical assistants still had issues with their positions since they were on either sides of the patient stressing their positions during the procedure. CONCLUSION:The ETHOS chair system allows the surgeon to operate seated in comfortable position with ergonomic chest, arms, and back supports. These supports minimize surgeon fatigue and discomfort during pelvic laparoscopic procedures even when these procedures are longer than 120 minutes without consequence to the patient safety or detrimental effects to the surgical team.

PURPOSE: To demonstrate the feasibility of pure robotic retrocaval ureter repair. MATERIALS AND METHODS: A 33 year old female presented with right loin pain and obstruction on intravenous urography with the classical "fish-hook" appearance. She was counseled on the various methods of repair and elected to have a robot assisted repair. The following steps are performed during a pure robotic retrocaval ureter repair. The patient is placed in a modified flank position, pneumoperitoneum created and ports inserted. The colon is mobilized to expose the retroperitoneal structures: inferior vena cava, right gonadal vein, right ureter, and duodenum. The renal pelvis and ureter are mobilized and the renal pelvis transected. The ureter is transposed anterior to the inferior vena cava and a pyelopyelostomy is performed over a JJ stent. RESULTS: This patient was discharged on postoperative day 3. The catheter and drain tube were removed on day 1. Her JJ stent was removed at 6 weeks postoperatively. The postoperative intravenous urography at 3 months confirmed normal drainage of contrast medium. CONCLUSION: Pure robotic retrocaval ureter is a feasible procedure; however, there does not appear to be any great advantage over pure laparoscopy, apart from the ergonomic ease for the surgeon as well the simpler intracorporeal suturing.

Objetivo: Analizar nuestra experiencia en la aplicación de TVT-O, en la corrección quirúrgica de la incontinencia de orina de esfuerzo (IOE). Pacientes y Método: Seguimiento prospectivo de 135 pacientes sometidos a TVT-O en Clínica Las Condes. Resultados: La mediana de edad fue de 55 años (R: 38 a 74 años), IMC 27,5 (R: 23 a 34) y paridad vaginal 2 (R: 0 a 5). Mediana de tiempo operatorio 7 minutos (R: 4 a 15 minutos). Se presentó una complicación intraoperatoria, correspondiendo al paso de la cinta a través de la uretra. Durante el postoperatorio inmediato se presentaron 7 complicaciones (5 por ciento); cinco de ellas fueron sobrecorrección expresada por retención urinaria. En todas se reajustó la cinta por medio de procedimiento ambulatorio a las 48 horas. No hubo hematomas ni infección de la zona operatoria. El alta se dio a las 12 horas en los casos de TVT-O sin asociación a otra cirugía. En el postoperatorio tardío se registró una exposición de la cinta en la pared vaginal anterior. Seguimiento promedio para la serie fue de 10 meses, con un máximo de 16 meses. Se obtuvo la cura de la IOE en 128 pacientes (95 por ciento), mejoría en 5 (4 por ciento) y falla en 2 (1 por ciento). Conclusión: TVT-O es una técnica quirúrgica para el tratamiento de la IOE, con resultados muy promisorios. Sin embargo, de la misma forma que los otros tipos de TOT, requiere una evaluación a largo plazo respecto a su eficacia.

La cirugía laparoscópica es parte de la urología actual. Hoy en día se desarrolla una amplia variedad de procedimientos por este medio. Considerando la curva de aprendizaje, existe una dificultad esperable en lograr un buen entrenamiento de residentes en formación. El objetivo del presente trabajo es comunicar la experiencia en el entrenamiento laparoscópico de los residentes de urología en un centro universitario. Se revisaron los registros clínicos de los pacientes con cirugía urológica laparoscópica en el período comprendido entre julio 1999 y agosto 2003. Se registraron: datos demográficos, antecedentes, indicación quirúrgica, cirujano, información de la cirugía, evolución postoperatoria. En el período de estudio se realizaron 128 cirugías urológicas laparoscópicas, de las cuales 20 (16 porciento)fueron realizadas por residentes de urología en formación con experiencia laparoscópica en cirugía generaly/o en cirugía experimental y con ayuda directa de urólogos laparoscopistas. Diez pacientes de sexomasculino (50 porciento). La edad promedio fue de 49 años (r: 19-74). Se realizaron 7 nefrectomías (4 radicalespor tumor y 3 por atrofia renal hidronefrótica), 4 quistectomías renales, 3 linfadenectomías lumboaórticas, 3 biopsias renales, 1 nefroureterectomía, 1 suprarrenalectomía, 1 instalación de catéter de peritoneodiálisismás adherenciolisis. El tamaño promedio de los tumores renales fue de 6,3 cm. El tiempo operatorio promedio fue de 108 minutos (r: 30-240) y el sangrado de 74 cc (r: 0-800 cc). Se presentó una complicación grave (paciente con hígado cirrótico como hallazgo intraoperatorio que presentó hemorragia y coagulopatía). El alta fue a los 2,7 días promedio (r: 1-14). No se registraron conversiones. La docencia directa en cirugía laparoscópica permite obtener resultados que se comparan favorablemente a los comunicados en la literatura.
