[The double J catheter in the shock wave treatment of kidney calculi]. / Le cathéter double J dans le traitment par ondes de choc de la lithiase rénale.

Review of the literature concerning the use of Double J stents prior to extracorporeal shock were lithotripsy. The advantages and disadvantages of stenting are described together with the marked benefit derived from the pretreatment use of the stent. The authors also try to determine which stones are suitable for preliminary stenting, by noting the degree of stone mass.

[Percutaneous suprapubic bladder lithotripsy]. / Lithotripsie vésicale par voie percutanée sus-pubienne.

The authors present a case of multiple bladder stones in a patient with severe ankylosis of the lower extremities, treated via percutaneous suprapubic approach. The suprapubic tract was created with Teflon-coated dilators and an Amplatz tube and the stones were fragmented with the nephroscope and a pneumatic lithotriptor. The simplicity of the procedure and the ease of the manoeuvre accelerated the stone fragmentation process while avoiding unnecessary trauma of the urethra.
