Introduction: With increasing experience and advancing technology, endoscopy for UTUC has become more common. Endoscopic Combined Intrarenal Surgery (ECIRS) could be an option for patients with low-grade and large-volume UTUC that could be either anatomically or technically challenging to manage by retrograde flexible ureterorenoscopy. Materials and Methods: In this video , we describe, step by step, our ECIRS technique as applied to two selected clinical cases of UTUC. Conclusion: ECIRS could represent a useful approach to UTUC in selected cases. The advantage of the “endovision” puncture and dilation technique is in the avoidance of entering the renal calyx at the level of the tumor. In addition, the combined approach, compared to the purely percutaneous approach, allows access to, and treatment of, neoplasms located in all renal calyces.
_______________________________________________________________________________________Introduction and Objectives: Treatment of bulky lithiasis in continent and non-continent urine storage reservoirs has been widely described and debated (1). Less is known about the optimal treatment in patients with a Mitrofanoff conduit. If voiding in these patients is incomplete, leading to recurrent symptomatic bacteriuria, formation of large lithiasis can be a common long-term complication (2, 3). Materials and Methods: This video describes a 19-year-old woman who underwent major open surgery at the age of six, with the configuration of a continent intestinal reservoir with a Mitrofanoff conduit. In 2020, she was referred to our center with a large stone in the reservoir and a minor stone in the inferior left renal calyx. We decided to proceed using a percutaneous approach with an "endovision technique" puncture for the bladder stone, combined with a retrograde intrarenal surgery for the renal stone. The MIP System "M size" was used to perform the percutaneous procedure, thus allowing a single-step dilation. The puncture and the dilation were followed endoscopically with a flexible ureterorenoscope avoiding the use of x-rays. The procedure was carried out as follows. The first step consisted in the insertion of a hydrophilic guidewire through the Mitrofanoff conduit. A flexible ureterorenoscope was then inserted coaxial to the guidewire. The percutaneous puncture, using an 80G needle, was followed endoscopically. Two guidewires were inserted, the first as a safety guidewire and the second for the tract dilation. The "single-step" dilation technique using the MIP system was performed and followed endoscopically. For the bladder lithotripsy, a dual-action lithotripter that combines ultrasonic and mechanical energy was used. Finally, a flexible ureterorenoscope and a basket for the retrieval of a single inferior caliceal stone were used. The procedure ended after positioning a single J stent in the left kidney and a nephrostomy tube in the reservoir. Results: The operative time was 80 minutes and the fluoroscopy time was 6 seconds. Hemoglobin and creatinine serum levels remained stable after the procedure and the patient was discharged on the third post-operative day, after removing both the single J and the nephrostomy tube. Follow-up lasted 12 months, with no bladder or renal stone recurrence, maintaining good continence of the Mitrofanoff conduit. Conclusion:In patients who have undergone several major surgeries a mini-invasive approach is advisable, not only for the morbidity of an open approach, but also for the increased risk of complications while handling an intestinal reservoir. Regarding a pure endoscopic approach, the passage of a nephroscope or a cystoscope through the Mitrofanoff conduit, combined with the continuous traction during the lithotripsy, could damage and compromise its continence. For this reason, the percutaneous approach is the most suitable method in these specific and rare cases.
Objective: The major strengths of surgical treatment of benign prostatic hyperplasia with laser are reduced morbidity compared to endoscopic resec-tion. No studies analysed the different risk of intra/peri-opera-tive events between patients undergoing Thulium and GreenLight procedures.Materials and methods: We retrospectively reviewed 100 con-secutive cases undergoing GreenLight vaporization and Thulium procedures performed during the learning curve of two expert endoscopic surgeons. Pre-operative data, intra and post-opera-tive events at 90 days were analysed. Results: Patients on antiplatelet/anticoagulant therapy were pre-dominant in the Green group (p < 0.0001). Rates of blood trans-fusion (p < 0.0038), use of resectoscope (p < 0.0086), and tran-sient stress urinary incontinence were statistically higher in the Thulium group. On the contrary conversions to TURP(p < 0.023) were more frequent in GreenLight patients. Readmissions were more frequently necessary in GreenLight group (24%) vs. Thulium group (26.6%). The overall complica-tion rate in GreenLight and Thulium groups were 31% and 53%respectively; Clavien 3b complications were 13% in Thulium patients versus 1% in GreenLight patients.Conclusions: GreenLight and Thulium treatments show similar safety profiles. Randomized controlled trial are needed to better clarify the rate of major complications in Thulium group, and the incidence of post-operative storage symptoms in these patients’ populations.
Background The cysts of the male pelvic floor represent a rare clinical entity. Their origin is linked to an altered development of paramesonephric and mesonephric ducts during embryogenesis. Case presentation We report our experience regarding two patients presenting cysts of the ejaculatory system treated with open and mini-invasive surgery. The patients referred to our clinic with nonspecific symptoms and the diagnosis was obtained by radiological investigations. The patient treated with an open approach developed a pelvic purulent collection and a fistula of the prostatic urethra, managed with surgical drainage and prolonged bladder catheterization. On the other hand, the patient treated with laparoscopic approach did not develop any complications. No sexual or ejaculatory disorders were reported. Conclusions Patients with congenital cysts of the pelvic floor must be adequately informed about the risks and benefits of surgery and a careful counseling is mandatory before surgery. Treatment is recommended for symptomatic patients and an endoscopic approach is associated with a high rate of recurrence. A laparoscopic approach, when possible, is desirable.
