Antegrade pressure measurement of urinary tract in children with persistent hydronephrosis

INTRODUCTION: Dilation of urinary tract occurs without the presence of obstruction. Diagnostic methods that depend on renal function may elicit mistaken diagnosis. Whitaker (1973) proposed the evaluation of urinary tract pressure submitted to constant flow. Other investigators proposed perfusion of renal pelvis under controlled pressure, making the method more physiological and reproducible. The objective of the present study was to evaluate the results of the anterograde pressure measurement (APM) of the urinary tract of children with persistent hydronephrosis after surgery suspected to present persistent obstruction. MATERIALS AND METHODS: Along 12 years, 26 renal units with persistent hydronephrosis after surgery (12 PUJ and 14 VUJ) were submitted to evaluation of the renal tract pressure in order to decide the form of treatment. Previous radionuclide scans with DTPA, intravenous pyelographies and ultrasounds were considered undetermined in relation to obstruction in 10 occasions and obstructive in 16. APM was performed under radioscopy through renal pelvis puncture or previous stoma. Saline with methylene blue + iodine contrast was infused under constant pressure of 40 cm H2O to fill the urinary system. The ureteral opening pressure was measured following the opening of the system and stabilization of the water column. RESULTS: Among the 10 cases with undetermined previous diagnosis, APM was considered non-obstructive in two and those were treated clinically and eight were considered obstructive and were submitted to surgery. Among the 16 cases previously classified as obstructive, nine confirmed obstruction and were submitted to surgery. Seven cases were considered non-obstructive, and were treated clinically, with stable DMSA and hydronephrosis. CONCLUSIONS: APM avoided unnecessary surgery in one third of the cases and was important to treatment decision in 100%. We believe that this simple test is an excellent diagnostic tool when selectively applied mainly in the presence of functional deficit.

The Assessment of Functional Change in Ischemic Stroke Rat

OBJECTIVE: To investigate and quantify functional deficit in ischemic stroke rat. METHOD: Male Sprague-Dawley rats were divided into sham group and stroke group. Permanent cerebral ischemia was inflicted on the stroke group by occluding the middle cerebral artery (MCAO). The proportion of hind limb weight bearing pressure was also measured. The withdrawal threshold values in the hindpaws were measured by using von-Frey hair for seven days from the day before ischemia. RESULTS: The proportion of paretic hind limb pressure to whole hind limb pressure in stroke group was significantly reduced than sham group (p0.05). Garcia motor score of stroke group was reduced significantly than sham group in whole experimental session after MCAO (p0.05). CONCLUSION: Ischemic stroke in rats can lead to the reduction of pressure at paretic hind limb. The motor test for pressure weight borne on the paretic leg may provide functional information in the future studies with ischemic stroke rat.

Effect of Ultrasonic Therapy on Neurological Function after Cerebral Infarction / 中国康复理论与实践

@#Objective To investigate the effect of the ultrasonic therapy on the neurological function after cerebral infarction. Methods 223 cases with cerebral infarction were divided into two groups: treatment group and control group. Both groups received the similar treatment with drug, while the patients in treatment group were treated with the ultrasonic therapy. They were assessed with Clinical Neurological Functional Deficit before and after treatment. Results The scores of Neurological Functional Deficit of all patients decreased (P<0.05), and treatment group decreased more significantly than control group (P<0.05). The total effective rate in the treatment group was higher than that in control group (P<0.05). Conclusion The ultrasonic therapy is helpful for the functional recovery of the patients after cerebral infarction.
