Objective To assess examine the results of urinary system ultrasonography, uroflowmetry and voiding diary for children patients presenting with primary monosymptomatic enuresis nocturna. Patients and methods Patients aged 5-17 years with enuresis nocturna were retrospectively analyzed. Urinary system ultrasonography (USG), uroflowmetry (UFM), complete urinalysis and two-day voiding diary were recorded for all patients. Comorbid diseases and surgeries were determined with a detailed history. Results A total of 842 patients were identified. History of previous surgery was present in 113 (13.4%) patients. Abnormal USG findings were detected in 117 (13.9%) patients.Urinary system USG findings of 17 patients with urinary tract infection were abnormal. In the two-day voiding diary, the bladder volume was found to be equivalent to the expected bladder volume in 54.2% of the patients, while the bladder volume detected in the first uroflowmetry was low in 65% of the patients. Conclusion Although the patients do not have urinary system symptoms other than night urinary incontinence at the time of admission, there may be accompanying pathologies. In addition, we think that a voiding diary measurement that has been properly explained and described to the family may be more reliable in cases where UFM cannot be repeated.

Purpose To assess examine the results of urinary system ultrasonography, uroflowmetry and voiding diary for children patients presenting withday time urinary incontinence. Patients and methods Patients aged 5-17 years with day time urinary incontinence were retrospectively analyzed. Urinary system ultrasonography, uroflowmetry, complete urinalysis and two-day voiding diary were recorded for all patients. Comorbid diseases and surgeries were determined with a detailed history. Results A total of 1805 patients were identified. Abnormal USG findings were detected in 385 (21.3%) patients. The highest bladder capacity detected in the voiding diary was found to be below the expected bladder capacity in 41.2% of the patients, while the bladder capacity measured in the uroflowmeter was low in 65.4% of the patients. Urinary tract infection was detected in 315 patients in the complete urinalysis. Associated disease was seen in 401 patients with a detailed history. Conclusion We think that ultrasonographic evaluation in these patients should include the entire urinary system, since upper urinary system anomalies can be seen not only in the bladder but also in the upper urinary tract. We think that a well-prepared voiding diary provides sufficient data in terms of bladder volume instead of bladder volume measured by bladder ultrasonography and/or uroflowmetry.
