Objective:

To investigate correlation between ultrasonically calculated urinary bladder weight and lower urinary tract symptoms (LUTS).

Methods:

3D and 2D measurement of parameters necessary to determine bladder weight: Inner and outer radius of the bladder, in 10 male and 10 female patients with LUTS, with urinary bladder filled to at least 200 ml of urine volume.

Results:

Average urinary bladder weight in males was 53,8 g and in female patient was 45,2 g. We found no statistically significant difference between male and female patients, all with LUTS. We also found that patients in LUTS have hypertrophied bladder, which means that urinary bladder mass should be larger and results in an increase of blader weight and both inner and outer radius of the urinary bladder, that should be detected ultrasonographically, but not too much over of pre- determined variations of normal bladder weight.

Conclusion:

Estimation of urinary bladder weight should be considered as non-invasive approach to patients with LUTS. However, it is more plausible to measure only urinary bladder wall thickness ultrasonically than to calculate urinary bladder weight without built-in software.

Acute bleeding of the upper gastrointestinal tract is an urgent condition with high morbidity, and a significant mortality despite advanced diagnostics and therapy. The goal is to investigate the determinants of the severity of duodenal peptic ulcer bleeding. The research included 304 patients hospitalized for acute bleeding from the upper part of gastrointestinal tract in a five year period. They had been treated in the Clinical Hospital Center Bežanijska Kosa in Belgrade. The diagnosis was made via gastroduodenoscopy. Out of the 304 patients, 197 (65%) suffered from bleeding peptic ulcer. 144 (73,1%) patients suffered from bleeding duodenal ulcer, most frequently with bulbar localization 124/86 (12%); 78 (62,9%) with a duodenal bulb back wall lesion. 48 (35,1%) of the bleeding duodenal ulcers were in the Forrest Ib stage, in 68 (47,2%) patients the size of the ulcer lesion was between 1,1-2,0 cm. A statistically positive correlation was determined between the duodenal ulcer lesions and the intensity of the bleeding (p<0,005). With 68/79/86,1% patients treated endoscopically, haemostasis was successful, whereas in 13/19,1%, rebleeding was localized in 11/84,6% in the duodenum bulb bask wall.
