The study will be a prospective, randomized, non-inferiority, open-label study, to be carried out at the Cancer Institute of the State of São Paulo for 6 months and will include patients agreeing to voluntary participation upon signing an informed consent form.

All patients with urological neoplasms who have undergone low and medium complexity surgical procedures (e.g. prostate TUR, Bladder TURP, double-J passage, partial or total videolaparoscopic and open nephrectomies) at ICESP will be invited to participate. It will be excluded all patients undergoing emergency operations, outpatient procedures, major procedures, patients with probes or drains or no support for home telemedicine.A telemedicine platform for video conferencing will be used by the healthcare team at our institution. The information from the patient will be protected by security passwords following ethical and legal provisions.

The patient will be invited to participate in the study at the preoperative evaluation. If it agrees to participate, it will sign the agreement informed consent, and will be randomized in the Redcap® software to one of the study arms (post-operative consultations in person or telemedicine). Patient follow-up in the study will be carried out with the first post-surgery visit between 10 - 20 days after discharge, according to the type of consultation for which the patient was randomized pre-surgery. The main outcome assessed will be the degree of patient satisfaction assessed by using a Likert scale. For patients randomized to the telemedicine arm, the global perception of satisfaction in all aspects of the teleconsultation will be quantified through a Patient Satisfaction Assessment questionnaire served via telemedicine. It will also be evaluated the perception of security defined as security of personal information (Laws General Data Protection - LGPD) . For patients randomized to the in-person postoperative consultations arm, it will be applied an adapted questionnaire, based on QAS-Tele, in order to verify the degree of patient satisfaction in relation to their type of consultation and their interest in carrying out telemedicine consultations in the future.

Questionnaires will be administered to patients 5 to 10 days after the first post-operative return to evaluate the issues mentioned by members of the research team via telephone contact. In addition to this information, patients coming to the institution's emergency room will be quantified within a period of up to 30 days after surgery.

The secondary outcomes will be the number of unattended arrivals programmed at the institution, presence of postoperative complications graded according to the Clavien-Dindo classification, appointment's duration, number of exams requested by the attending physicians, total cost involved per service (expenses with travel, mobile internet data package, necessary structure to telemedicine services) and environmental impact generated with both types of services. Patients will have their demographic data and clinical conditions recorded in appropriate database using RedCap software (Sex, Age, index of body mass, classification of the American Society of Anesthesiologists, Charlson classification, Clavien-Dindo classification). The descriptive analysis will be made by reporting the quantitative variables through the mean, standard deviation, median and quartile, and statistical analysis performed using the Wilcoxon-Mann-Whitney.

hyaluronic acid-carboxymethylcellulose

To assess the anti-adhesive effect of treatment with hyaluronic acid-carboxymethylcellulose following laparoscopic pelvic surgery (radical prostatectomy).

Methods This was a prospective, randomized, controlled, single-blind, parallel-group study using HA/CMC (marketed as Guardix-sol®, Hanmi Medicare, Seoul, Korea) in patients who underwent laparoscopic radical prostatectomy between November 2011 and June 2014. All the patients were informed in detail about the aims and the procedures of the study and they signed a written informed consent prior inclusion into the study. The protocol and the written informed consent were approved by the local ethical committee (Catholic Medical Center, Clinical Research Coordinator Center; approval number XC11DIMI10098H).

Subjects Men who were 50-75 years old and diagnosed with prostate cancer were eligible if they were scheduled to undergo laparoscopic radical prostatectomy. Exclusion criteria included any history of abdominal or pelvic surgery, hypersensitivity or an allergic reaction to the study material, pelvic lymph node dissection at the same time as prostatectomy, the presence of surgical site infection or contamination, a history of a medical disease causing bowel adhesion, or a history of severe drug allergies.

Study design and protocol The laparoscopic radical prostatectomy was performed in same surgical procedures and steps by two surgeons (USH and JSK) who have experienced over 150 cases of laparoscopic radical prostatectomy. The laparoscopic radical prostatectomy was performed using the five-port fan-shaped transperitoneal approach. After the introducing the peritoneal cavity, incising the parietal peritoneum between the medial umbilical ligaments are incised and dissection is carried through the fatty alveolar tissue to develop the space of Retzius. After that, the surgical steps are following order (1) incision of the endopelvic fascia; (2) ligation of the dorsal vein complex; (3) division of the bladder neck; (4) dissection of the seminal vesicles; (5) incision of the Denonvillier fascia and control of the lateral pedicles with antegrade neurovascular bundle dissection; (8) apical dissection and division of the dorsal vein and the urethra; (9) urethrovesical anastomosis.

Considering about 30% of dropout rate (under the assumption of 40% difference between HA/CMC treatment group and the control group based on previous similar study, by which the target enrollment for this trial was 60 subjects (30 subjects per group). The sample size was determined assuming a level of significance of α=0.05 (two-side) and a 80% statistical power of test. All patients were randomly assigned to either the HA/CMC treatment group (n=30) or the control group (n=30) using a computer-generated randomization table. The surgeon was blinded to treatment assignments before randomization. Patients were also blinded to their treatment group throughout the study. HA/CMC was applied in all port sites and the peritoneal incision line of the medial umbilical ligament with a single-use applicator attached to a sprayer that allowed for the precise application to the required sites. The amount of HA/CMC applied was 5 ml. Information regarding the duration of illness and medical history were collected at the time of enrollment (V0). Viscera slide ultrasound and plain X-ray were recorded at the time of the operation (V0) and 12 (V1) and 24 week (V2) after the operation.

The primary end point was the difference in excursion distance on viscera slide ultrasound between V0 and V2. The secondary end point was excursion distance on viscera slide ultrasound at V2 and the presence of restriction of viscera slide on ultrasound at V2.

Assessment of efficacy and safety Twelve and 24 weeks after the operation, bowel adhesion to the abdominal wall was evaluated by ultrasound and plain X-rays. We performed viscera slide ultrasound according to a technique that has been previously described. By dividing the abdomen into 5 segments and examining the viscera slide in each segment, a prediction of the extent of the adhesions was made for each patient. At the time of the viscera slide ultrasound, data were also collected on the location of the scars on the abdomen. The main point of interest was the distance of the longitudinal excursion of the selected area in relation to the fixed abdominal wall. Normal viscera sliding movement was defined as equal to or greater than 1 cm of longitudinal movement. Restricted viscera slide was defined as less than 1 cm of longitudinal movement during both normal and exaggerated respiration. The ultrasound was performed by two sonographers who had been well instructed for study assessment. The assessment by ultrasound was double-checked. The sonographer, radiologist and all accessor was blind to the randomization during the all study period.

Statistical Analysis The data for this study are expressed as mean ± standard deviation of the mean. The comparisons of the 2 groups were made using a chi-test, an independent Student's t test, or repeated measure ANOVA. P-values \<0.05 were considered significant. Statistical calculations were carried out with IBM SPSS statistics, Version 21 (IBM Corp, Armonk, NY).
