[Characterization of urinary tract symptoms and quality of life in patients with double-pig-tailed ureteral stents]. / Evaluación de clínica y calidad de vida con catéteres ureterales de tipo doble pig-tail.

OBJECTIVES: To prospectively assess the prevalence of urinary tract symptoms caused by indwelling ureteral stents and how they affect their quality of life using an specific questionnaire.

RESULTS: 46 men and 54 women, mean age 54 years, completed the study. Mean time after stent insertion was 6.5 weeks. The cause of the insertion was in 40% due to the size of the stone, previous to ESWL, 33% due to urinary tract obstruction, 25% due to infection, and the others after a surgical procedure. 95% of patients with stent positioning without general anesthesia complaint of pain during the procedure. 89% of patients reported bothersome urinary symptoms, named in order of frequence: nycturia, frequence voiding, incomplete empting, dysuria, urgence, haematuria and incontinence. More than 70% of patients experienced pain that impaired daily activities, in 52% pain was located at the flank and in 47% at the bladder. 60% of patients signalled that they were not satisfied with their quality of life with the indwelling catheter.

[Clinical experience and results of ESWL treatment for 1.000 consecutive patients with the Siemens Lithostar Modularis]. / Lithostar Modularis de Siemens: exposición de los resultados de los 1.000 primeros pacientes.

PATIENTS AND METHODS: We describe the outcome of the treatment of 1.000 consecutive patients treated since may 2000 to december 2003 with Siemens Lithostar Modularis to evaluate the efficacy of this new lithotripter RESULTS: 60.5% male and 39.5% female's patients were treated. Average age of 53.5 years old. 44.1% of the urinary stones were located on the right side and 55.9% on the left. The mean size of the stones was 1.22 +/- 0.74 cm with 59% lesser than 1 cm, 27.6% between 1 and 2 cm and 13.4% bigger than 2 cm. Mean number of sessions required were 1.6. There were differences in the number of sessions related to the size of the lithiasis, 1.3 session in the group of lithiasis smaller than 1 cm and 2.01 sessions in the group bigger than 1 cm. The stones that required less number of sessions were located in the ureter and upper calyx. 71.2% of the patients were stone free after one treatment. CONCLUSIONS: Siemens Lithostar Modularis has the adventages of a great confort of the patient during the procedure, better image because of a very good cuality of the fluoroscopy and the main point is a great comminution of the stone doing very easy the elimination of the fragments achieving a stone free rate of more than 90% in our experience, decreasing the need of auxiliary manoeuvres and the leng of the treatment.
