Efficacy of flexible ureterorenoscopy with holmium laser in the management of calyceal diverticular calculi.

The purpose of this study was to evaluate the efficacy and safety of flexible ureteroscopy with holmium laser lithotripsy in the management of calyceal diverticular calculi. In this study, we retrospectively analyzed the clinical data of 27 patients with calyceal diverticular calculi admitted to the Department of Urology of the Zigong First People's Hospital from May 2018 to May 2021. Intraoperatively, the diverticular neck was found in all 27 patients, but flexible ureterorenoscopy lithotripsy was not performed in 2 cases because of the slender diverticular neck, and the success rate of the operation was 92.6%. Of the 25 patients with successful lithotripsy, the mean operative time was 76.9 ± 35.5 (43-200) min. There were no serious intraoperative complications such as ureteral perforation, mucosal avulsion, or hemorrhage. Postoperative minor complications (Clavien classification I-II) occurred in 4 (16%) patients. The mean hospital stay was 4.4 ± 1.7 (3-12) days. The stone-free rate was 80% at the 1-month postoperative follow-up. After the second-stage treatment, the stone-free rate was 88%. In 22 cases with complete stone clearance, no stone recurrence was observed at 5.3 ± 2.6 (3-12) months follow-up. This retrospective study demonstrated that flexible ureterorenoscopy with holmium laser is a safe and effective choice for the treatment of calyceal diverticular calculi, because it utilizes the natural lumen of the human body and has the advantages of less trauma, fewer complications, and a higher stone-free rate.

Rare neonatal malignant primary orbital tumors: Three case reports.

BACKGROUND: Aggressive malignant primary orbital tumors are extremely rare in newborns. The current cases further clarify the clinical features of malignant primary orbital tumors in neonates. CASE SUMMARY: At the time of presentation at the Seventh Center of People's Liberation Army General (PLAG) Hospital, the children were 1-, 2- and 5-mo-old, respectively, and included 2 boys and 1 girl. All three cases had unilateral proptosis at birth, and underwent mass excision and histopathologic examination. A peripheral primary neuroectodermal tumor, an aggressive infantile fibromatosis and an embryonic rhabdomyosarcoma were diagnosed, respectively. The first case underwent routine chemotherapy following surgery but died within three months due to worsening condition as the tumor spread throughout the body. The other two children were treated by surgery, and at the follow-up visits 6 mo and 1 year after surgery, respectively, the wound was completed healed, and they had normal growth and development without radiotherapy or chemotherapy. A review of highly uncommon orbital tumors in newborns is also provided. CONCLUSION: Malignant primary tumors should be considered in the presence of unilateral proptosis in newborns.
