為了分析糖尿病患者其膀胱功能障礙在尿路動力學及在臨床上的表現，我們收集了62位有排尿障礙糖尿病患者的臨床病史以及實驗室數據來作分析，並和他們的尿路的動力學檢查作比較。所有這62位糖尿病患者都是有泌尿道症狀，而他們照會泌尿科醫師的原因是頻尿（36位），尿瀦留（16位）排尿困難（23位）以及尿失禁（9位）。部份患者有一項以上的泌尿道症狀。我們發現除非有尿路動力學檢查，否則我們無法由臨床症狀準確地預測其膀胱功能。在本研究的族群中，膀胱容量大於500毫升的有19位病人（30.6%），而膀胱第一次漲尿感覺大於250毫升的共有17位病人（27.4%）。膀胱不自主收縮以及膀胱收縮能力低下兩者都可以在糖尿病患者觀察到。膀胱不自主收縮的病人共佔33.9%，膀胱收縮能力低下者29%。當糖尿病病史小於10年時，糖尿病的控制好壞和膀胱功能正常與否有統計學上顯著的相關(p值=0.019)，但糖尿病病史長過10年者則無統計學上的差異。不論糖尿病控制的好或壞，膀胱功能正常與否都和糖尿病病史的長短無關。有膀胱功能障礙的患者並不只有“膀胱功能低下”單一種的表現。唯有同時考慮到病人的病使，症狀的表現，以及尿路動力學檢查的結果，方能較可靠地去評估及診斷糖尿病患者的膀胱功能障礙。

In an attempt to evaluate the urodynamic parameters and the clinical features of urinary bladder dysfunction in patients with diabetes mellitus (DM), 62 diabetic patients’ clinical histories and laboratory data were analyzed and correlated with the parameters of urodynamic studies All 62 patients were symptomatic, with chief problems of urinary frequency (36 cases), urinary retention (16 cases), dysuria (23 cases) and urinary incontinence (9 cases). Some of them had more than one urinary symptom. These outcome did not permit accurate predication of the detrusor function solely from the clinical symptoms without urodynamic results. There were only 19 patients (30.6%) who had a bladder capacity greater than 500 ml, and only 17 patients (27.4%) experienced a first sensation larger than 250 ml. Both poor (21 cases) and involuntary (18 cases) contractions of the detrusor were observed in the patient group. The relationship between DM control results and the detrusor function was statistically significant for those patients with a DM history of 10 years or less (p=0.019) but not for those with more than 10 years. Detrusor function did not correlate with DM duration in patients with both good and poor DM control results. This study found that diabetic cystopathy is not only hypotonic in nature. A combination of the patient’s history, symptom complex and urodynamic studies are required to evaluate and diagnose diabetic voiding dysfunction.
