The Comparison of Valsalva and Cough-induced Leak Point Pressures in Patients with Stress Urinary Incontinence / 대한비뇨기과학회지

PURPOSE: We evaluated Valsalva and cough-induced leak point pressure measurements identically and compared their reliability in the patients with stress urinary incontinence (SUI). MATERIALS AND METHODS: Seventy-five patients complaining of SUI were assessed with medical history, uro-gynecological examination, any factors that could affect voiding symptoms, and videourodynamic study consisting of Valsalva leak point pressure (VLPP), cough-induced leak point pressure (CILPP) on supine and erect position, prospectively. We observed the location and descent of bladder neck on fluoroscopic images, and VLPP, CILPP synchronously. The bladder neck position, the degree of bladder neck descent, VLPP and CILPP were compared, then the correlation of each was analysed. RESULTS: The lower the position of initial bladder neck is, the more severe the descent of the bladder neck is in supine (Valsalva; r=0.305, p0.05). VLPP and CILPP in SUI type III are significantly lower than those in SUI type I and II (p<0.05), but VLPP and CILPP were not correlated to subjective symptoms of SUI. CONCLUSIONS: Both VLPP and CILPP are reliable in evaluation of SUI. However, ecause VLPP is reliable regardless of position and easier than CILPP in the measurement, it is expected as more useful method. If CILPP is used, it must be evaluated in the erect position.

Primary Renal Lymphoma in a Child / 대한비뇨기과학회지

Primary renal lymphoma is a controversial entity and extremely rare disease, possibly due to the fact that the kidney is one of the extranodal organs usually not containing lymphoid tissue. It is unclear if this conditions can be diagnosed preoperatively with imaging studies. In most cases the diagnosis is made after removal or biopsy of a kidney for suspected primary renal tumor or at autopsy. Treatment usually consists of surgery and chemotherapy with or without radiation therapy and the prognosis is poor. We report a case of primary renal lymphoma presenting with fever in a 13-month- old boy who was treated with surgical intervention and combination chemotherapy.
