Side percutaneous access in the renal lithiases treatment

A nefrolitotripsia percutânea (NP) é uma das principais formas de tratamento de cálculos renais volumosos. O acesso percutâneo lateral é feito com o paciente em decúbito dorsal horizontal. O estudo objetivou avaliar os resultados de acesso lateral, em posição modificada, no tratamento percutâneo de cálculos renais e também o mesmo associado ao ureteroscópico, em caso de cálculos renais e ureterais concomitantes. Estudou-se 88 pacientes e os resultados foram considerados bem sucedidos em 69,32%. As complicações mais comuns foram febre e sangramento. Concluímos que a NP com acesso lateral apresenta sucesso no tratamento da litíase oferecendo vantagens no posicionamento para realização de procedimento associado à ureteroscopiaPercutaneous nephrolithotripsy (PN) is one of the main alternatives for the treatment of large renal stones. The present study aimed to evoluate the results of the lateral percutaneous approach, in a modified position, for the treatment of kidney stones. We also evaluated the association of the percutaneous with the uretroscopic treatment in patients with concomitant kidney and ureteral stones. A total of 88 patients selected, 69,32% of patients were considered complete success. The most common complication was the development fever and bleeding. In conclusion the PN using the lateral approach is a safe procedure with a high success rate in the treatment of kidney stones and is a advantageous, for patient positioning especially for the performance of ureteroscopic procedure

Management of Chronic Unilateral Hematuria by Ureterorenoscopy

Background and Purpose: Chronic unilateral hematuria is characterized by intermittent or continuous gross hematuria that cannot be diagnosed using standard radiology and hematology methods. In the past, it was managed with partial or total nephrectomy. In the age of minimally invasive procedures, however, endoscopy has enabled more accurate diagnosis and management. We analyzed our experience with transurethral ureterorenoscopy using a flexible ureteroscope to determine the feasibility and success of endoscopic management of renal hematuria. Patients and Methods: We reviewed the records of 13 patients who presented with chronic unilateral hematuria, in whom radiologic and laboratory tests failed to reveal the source of bleeding. In the cases in which the lesion was identified, after complete inspection of the collecting systems, the bleeding site was treated ureteroscopically with a holmium: yttrium-aluminum-garnet ( YAG) laser. Results: Follow-up ranged from 4 to 60 months ( mean 26 mos). During the follow-up of the 13 patients, 11 remained symptom-free, with only one session of flexible ureterorenoscopy necessary. Relapse occurred in two patients after 4 months and 6 months, respectively; during a second session of flexible ureteroscopy, the bleeding site was successfully identified and cauterized with a holmium: YAG laser. No surgical complications occurred. Conclusions: Conservative treatment of patients with chronic unilateral hematuria should always be considered. Laser ureteroscopic treatment is an excellent method and should be considered as the first option for the management of chronic unilateral hematuria
