ABSTRACT
To compare totally tubeless and standard percutaneous nephrolitotomy procedures on many parameters. Percutaneous nephrolitotomy was performed on 195 patients between June 2009 and May 2012. The data of those patients were evaluated retrospectively. Totally tubeless cases were enrolled to Group 1, and Group 2 consisted of non-tubeless cases (re-entry or Foley catheter). Group 1 included 85 cases and group 2 a total of 110 patients. Paper tracing values for the kidney stones were 321.25 ± 102.4 mm2 and 324.10 ± 169.5 mm2 respectively. Mean fluoroscopy time was 4.9 ± 1.9 min and 5.08 ± 2.7 min, mean operation time was 78.8 ± 27.9 min and 81.9 ± 28.77 min and mean decrease in hematocrit was 2.6 ± 1.6 and 3.74 ± 1.9 respectively. All these comparisons were statistically significant. Length of hospitalization was 1.6 ± 1.1 and 3.5 ± 1.5 days for Groups 1 and 2 respectively. Mean superficial pain score was 5.8 ± 1.6 and 6.7 ± 1.2 respectively for both groups after 1 hour. At 6 hours, the scores changed to 3.87 ± 1.22 and 4.84 ± 1.3 respectively. The analgesic dose was 1.00 ± 0.7 and 1.53 ± 0.6 for the groups respectively at 6 hours. All the statistical differences were significant for these three parameters. We believe that, because of their post operative patient comfort and decreased length of hospital stay, totally tubeless procedures should be considered as an alternative to standard percutaneous nephrolitotomy.

Introduction: To report a patient with a history of bariatric surgery and staghorn calculi of the left kidney, who had a colonic perforation after percutaneous renal surgery. Material and Methods: A 38 years old male patient, with a history of gastric bypass, underwent a left percutaneous nephrolithotomy due to staghorn renal calculi. In the procedure, the colon was incidentally perforated during the percutaneous access. Results: The patient developed a sepsis and fecal material appeared surrounding the nephrostomy tube. A transverse colostomy was performed, with improvement of the sepsis and a spontaneous resolution of the nephro-colonic fistula. Conclusion: Is known that bariatric surgery is associated with the novo urinary lithiasis. Besides, there are anatomical changes in between intraabdominal viscera. Radiological studies and a adequate surgical strategy are fundamental to avoid severe surgical complications in kidney stone disease.
Objetivo: Presentar el caso de un paciente con antecedente de cirugía bariátrica y litiasis renal coraliforme, el cual presentó una perforación colónica luego de una nefrolitectomía percutánea. Material y Métodos: Paciente hombre de 38 años de edad con antecedente de bypass gástrico. Fue sometido a una nefrolitectomía percutánea por litiasis renal izquierda coraliforme, complicada de una perforación colónica no reconocida en forma precoz. Resultados: El paciente evolucionó con cuadro séptico y presencia de material fecaloídeo en la zona de la nefrostomía, por lo que requirió colostomía transversa, con resolución de la complicación séptica y resolución de la fístula nefrocólica. Conclusión: Es sabido que la cirugía bariátrica se asocia a litogénesis urinaria y cambios anatómicos de las relaciones de los órganos abdominales. El estudio radiológico y la adecuada estrategia quirúrgica evitará complicaciones graves en la cirugía de la litiasis renal.
