Introduction: Large bladder calculi are common in developing countries. The aim of this study was to descriptively evaluate the percutaneous suprapubic cystolithotomy surgery in patients with bladder calculi larger than 3 cm. Methods: In this descriptive study, information were collected from the questionnaires before and after surgery and also from the records. Data were analyzed using the software SPSS on the levels of descriptive and inferential statistics. Results: A total of 110 patients participated in this study. The females comprised 34.5% of the patients. The mean age of the patients was 36.53 ± 25.39 years. All patients were examined in two groups of children (34.5%) and adults (65.5%). Prolonged hematuria was observed in 13.3% of children and 8.3% of adults, cystostomy tube placement occurred in 2.6% of children and 5.6% of adults, and urinary leakage happened in 4.2% of adults. The mean decrease of hemoglobin in adults (0.62) was more than that in children (0.43). With increasing age, the size and number of calculi as well as hemoglobin downfall increased in the patients. The calculus size was larger in men than in women. The duration of hospitalization increased with increasing complication rates. The length of hospitalization and decrease in hemoglobin elevated with increases in the number and size of calculi in adults. Patients with urinary leakage complained of more pain. As the number of calculi rose, prolonged hematuria increased.
Conclusion: The percutaneous suprapubic cystolithotripsy surgery is a safe and effective treatment for bladder calculi in children and adults.
