[Staghorn calculi. Combined treatment with percutaneous nephrolithotripsy and extracorporeal lithotripsy]. / Litiasis coraliforme. Tratamiento combinado con nefrolitotricia percutánea y litotricia extracorpórea.

We present our experience in 61 patients with partial or complete staghorn stone who underwent combined treatment with PCN and ESWL. We excluded the cases with an additional factor complicating staghorn stone, such as horseshoe kidney, severe ectopic, mal-rotated or high, with pyeloureteral junction stricture, etc. The patients were submitted to 72 PCN and 113 ESWL sessions, 5 percutaneous nephrostomies prior to PCN and 5 ureteroscopy procedures to remove post-ESWL obstruction. Complications were observed in 24.5%; acute urinary infection post-PCN (13 patients, 21.3%), massive absorption of liquid (1 case) and arteriovenous fistula (1 case). One year following treatment 83.6% of the patients are stone free and 14.9% have residual stone fragments. No patients developed arterial hypertension and one patient was submitted to nephrectomy due to pyelonephritic atrophy. Our criteria concerning the indications for the different therapeutic methods are discussed. In our view, the role of each method must be reviewed in the light of current clinical experience and investigative data.

[Percutaneous nephrostomy associated with extracorporeal shockwave lithotripsy in the treatment of renoureteral lithiasis]. / Nefrostomía percutánea asociada a litotricia extracorpórea por ondas de choque en el tratamiento de la litiasis renoureteral.

From a series of 5000 cases that had undergone extracorporeal shock wave lithotripsy at the Hospital Clinico Quirúrgico "Hermanos Ameijeiras" from March, 1986 to April, 1988, 220 cases that required percutaneous nephrostomy due to obstructive hydronephrosis from stone fragments were studied. We analyzed the clinical, radiological and ultrasound features of these cases, as well as the criteria for performing percutaneous nephrostomy. We identified the risk factors that made the procedure necessary, particularly urinary tract infection. No important complications ascribable to the foregoing procedure were observed. Performing the procedure early improved patient clinical course and reduced cost of treatment. To eliminate stone fragments completely, percutaneous nephrostomy was combined with other procedures in 198 cases (90%). The stone fragments were passed spontaneously in 10 cases (4.5%) following diversion. At 2 months 190 cases (86%) were completely stone free, 18 (8%) had residual stones and 12 (6%) required open surgery. The foregoing results show that percutaneous nephrostomy is a very useful procedure in septic-obstructive complications following extracorporeal shock wave lithotripsy and acquiring the skill to perform it is essential.
