RESUMO
PURPOSE: We aimed to compare the outcomes of pneumatic (PL), ultrasonic (UL) and combined (PL/UL) lithotripsy performed in percutaneous lithotripsy (PNL) according to success rates and stone clearence. MATERIALS AND METHODS: The medical records of 512 patients treated with PNL between April 2010 and April 2013 were evaluated. Postoperative stone analysis revealed as calcium oxalate in 408 of these patients. The operation notes of 355 patients recorded in detail with complete parameters were reviewed. According to stone disintegration method, patients were divided into three groups: PL only in Group I, UL only in Group II, and UL/PL combination in Group III. Number of patients was 155, 110 and 90, respectively. RESULTS: Fluoroscopy screening time was significantly shorter in group II, and III compared to group I (p<0.001). The failure rates were 13.5% (21 patients) for group I, 3.6% (4 patients) for group II, and 3.3% (3 patients) for group III. There was a significant statistical difference in favor of group II and III by means of success (p=0.023). Group II and III had larger FSA, and this was statistically significant (p=0.032). Stone disintegration time (SDT) was 64.0 ± 41.92 minutes for group I, 49.5 ± 34.63 for group II, and 37.7 ± 16.89 for group III. Group III has a statistically significant shorter SDT (p=0.011). CONCLUSIONS: We concluded that, in cases with high stone burden, where faster and efficient lithotripsy is needed, combined ultrasonic / pneumatic lithotripter may be the ideal choice and in suitable cases ultrasonic lithotripter usage provides important advantages to the surgeon.

OBJECTIVES: To determine the clinical importance of fibrosis on pelvic magnetic resonance imaging in patients with postprostatectomy incontinence (PPI) due to sphincteric incompetence. METHODS: Urethral and periurethral fibrosis was determined by pelvic magnetic resonance imaging in patients who did (n = 22) or did not (n = 14) have urinary incontinence after transurethral resection, transvesical prostatectomy, or radical retropubic prostatectomy. The relation between fibrosis and the duration of incontinence, pad weight, symptom score, cystoscopy findings, and urodynamic findings was examined. RESULTS: Fibrosis was seen in all patients (22 of 22) in the study group and in 4 of 14 patients in the control group (P <0.001). All the patients with severe fibrosis had undergone radical retropubic prostatectomy (P <0.001). Similar to the etiology for incontinence, no relation was found between the severity of fibrosis and the duration of incontinence, pad weight, symptom score, cystoscopy findings, or urodynamic findings. However, the duration of incontinence was shorter in patients with mild fibrosis, clinically. CONCLUSIONS: The results of our study have shown that the incidence of fibrosis is much greater in patients with PPI than in patients without PPI. Consequently, we believe that fibrosis plays an important role in the development of PPI because it may have a negative effect on external urethral sphincter function.
