摘要

Aim

In recent years, the incidence of nephrolithiasis in the paediatric population appears to be increasing. Aim of this study was to evaluate the effectiveness of the twin-surgeon model on the paediatric stone patients of our centre.

Methods

A retrospective study with data retrieval from our electronic patient system was conducted; it included a total of 41 patients up to 18 years of age diagnosed with renal calculus.

Results

From 2004 to 2024 29 male and 12 female were retrieved. The average age for females was slightly higher than males; 9.92 vs. 7.78. Pain was the main symptom for most patients. Of them 36.6% were treated conservatively as stone spontaneous passage occurred. Twenty nine underwent surgical treatment using the twin-surgeon model. The surgically treated patients were had stones with average size 10.1 mm; they underwent either a percutaneous nephrolithotomy or flexible ureteroscopy and lasertripsy and in 2 cases with pelvic ureteric obstruction an open stone retrieval was performed. Preoperative stent placement was needed in 7% of patients, whereas 41.5% had a stent implanted postoperatively for 7–19 days. 53.8% of the surgical treated patients were stone free and 96.4% symptom free at follow-up.

Conclusions

Endoscopic stone removal using the twin surgeons model is safe and effective for stone size 2-3 cm. This treatment management enables a local treatment of children from a multidisciplinary urology team addressing effectively the special characteristics of stones during the paediatric age.
