The aim of this study was to assess the effect of simple renal cysts on extracorporeal shockwave lithotripsy (SWL) in patients with calyceal renal calculi. Patients with simple renal cysts >35 mm and ipsilateral renal calculi 40 years that had renal calculi 0.05), which was 33.3% in group 1 and 68.2% in the control group (P = 0.017). The presence of renal cysts in a patient with calculi requires that an individualized treatment plan be devised, so as to provide the patient with the most effective treatment.

This comparison between patients with and without large cysts in terms of stone free rates after SWL is welcome. Large cysts that compress the calyx neck will theoretically result in a lower chance of fragment clearance. It was accordingly found that the stone-free rate was twice as good in patients without cysts. The lesson learnt is that when large cysts are found adjacent to stone-bearing calyces, cyst puncture is indicated.
This is a procedure that I personally successfully have used to improve the treatment result in some patients.
