Introduction: Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele. Case presentation: We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy. A literature review was also conducted. Discussion: The pathogenesis of ureteroceles is not well understood, however many proposed mechanisms exist with the incomplete dissolution of chwalla membrane being the most accepted one. The type of ureterocele and age at presentation will help guide the appropriate investigation and management, nevertheless certain goals of treatment should apply to all cases. Adult ureterocele is usually clinically silent but it may co-exist with other conditions such as a ureteral calculus and in these conditions it can be managed endoscopically. Conclusion: Ureteroceles complicated by stones can be effectively managed with endoscopic resection or incision of the ureterocele coupled with stone removal, however long term follow up is required to monitor for hydronephrosis and iatrogenic vesicoureteric reflux.

Background and Objectives: Elderly patients constitute a large segment of healthcare receivers. Considering the functional deterioration of multiple organ systems with aging, achieving a safe perioperative approach is challenging. Our aim is to study the safety and effectiveness of a genuinely regimented co-induction technique in order to minimize anesthesia-related complications. Materials and Methods: One hundred and five patients were assigned to three groups according to the induction technique: propofol, sevoflurane and co-induction group. Inclusion criteria: patients with age ≥65 and American Society of Anesthesiologists physical status classification (ASA) II-III who underwent endoscopic urological procedures. The propofol group received a dose of 1.5 mg kg⁻¹ of propofol over two minutes for induction. The sevoflurane group received 8% of sevoflurane and 100% oxygen through a plastic facemask with the fresh gas flow set at 8 L min⁻¹. The co-induction group received 4% sevoflurane through plastic facemask for two minutes, followed by a 0.75 mg kg⁻¹ dose of propofol. After ensuring full range jaw relaxation, the laryngeal mask airway (LMA) was inserted. Results: Overall, the co-induction technique had a favorable profile in terms of respiratory adverse events, while the sevoflurane group had a favorable profile in terms of hemodynamic stability. Furthermore, 24 (68.6%) patients receiving inhalational sevoflurane had episodes of transient apnea, which constitutes 77.4% of the 31 episodes of transient apnea in the studied sample (p < 0.001). Moreover, six (17.1%) patients in the sevoflurane group had an episode of partial laryngospasm (p = 0.034). Compared with the co-induction group, we found that the propofol group had significantly less systolic and diastolic blood pressures in the second minute, with p values of (0.018) and (0.015), respectively. Conclusions: The co-induction technique utilizing 4% sevoflurane at 8 L min⁻¹ flow of oxygen inhaled over two minutes followed by 0.75 mg kg⁻¹ of propofol achieved less respiratory adverse events compared with the sevoflurane group, and less hemodynamic instability compared with the propofol group.
