Study Type – Practice patterns (retrospective cohort) Level of Evidence 2b OBJECTIVE • To evaluate the safety and feasibility of laparoscopic adrenalectomy (LA) performed in several German centres with different laparoscopic experience, as LA has become the gold‐standard approach for benign surgical adrenal disorders; however, for solitary metastasis or primary adrenal cancer its precise role is uncertain. PATIENTS AND METHODS • The data of 363 patients who underwent a LA were prospectively collected in 23 centres. • All centres were stratified into three groups according to their experience: group A (<10 LAs/year), group B (10–20 LAs/year) and group C (>20 LAs/year). • In all, 15 centres used a transperitoneal approach, four a retroperitoneal approach and four both approaches. • Demographic data, perioperative and postoperative variables, including operating time, surgical approach, tumour size, estimated blood loss, complications, hospital stay and histological tumour staging, were collected and analysed. RESULTS • The transperitoneal approach was used in 281 cases (77.4%) and the retroperitoneal approach was used in 82 patients (22.6%). • In all, 263 of 363 lesions (72.5%) were benign and 100 (27.5%) were malignant. • The mean (sd) operating time was 127.22 (55.56) min and 130.16 (49.88) min after transperitoneal and retroperitoneal LA, respectively. • The mean complication rates for transperitoneal and retroperitoneal LA were 5% and 10.9%, respectively. CONCLUSION • LAs performed by urologists experienced in laparoscopy is safe for the removal of benign and malignant adrenal masses. LA for malignant adrenal tumours should be performed only in high‐volume centres by a surgeon performing at least >10 LAs/year.

The combined use of percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy in patients with staghorn calculi has become an established treatment regimen. We evaluated the results of 90 staghorn calculi-bearing kidneys treated with such combination therapy after a mean follow-up of approximately 2 years. A total of 69 kidneys (76.7 per cent) became free of stones at some point after treatment. However, due to stone recurrence this number decreased to 55 kidneys (61.1 per cent) at the end of follow-up. Patients who had undergone a previous open operation on the stone-bearing kidney showed less favorable results than the over-all group. When our results were compared to reported data on open surgery or percutaneous nephrolithotomy alone even better results may have been obtained by such treatment modalities. However, our data indicate that percutaneous stone debulking combined with further destruction of residual stone fragments by shock wave lithotripsy certainly is less invasive than an open operation and provides an alternative to percutaneous treatment alone, which can yield comparable results.
