ABSTRACT
Objective:To observe any effect of functional magnetic stimulation (FMS) of the sacral 3 nerve root on relieving urine retention after a spinal cord injury.Methods:Forty-four patients with neurogenic bladder disorders after a spinal cord injury were divided at random into a 5Hz group ( n=14), a 20Hz group ( n=15), and a sham stimulation group ( n=15). In addition to conventional bladder control training, the 5Hz and 20Hz groups were given 20 minutes of FMS of the sacral 3 nerve root at the appropriate frequency five days a week for 4 weeks. The sham stimulation group was not given any stimulation. A detailed urination diary was kept during the treatment, and before and after the 4 weeks, everyone′s bladder pressure volume was assessed and an electromyogram was recorded. Results:After the treatment those in the 5Hz and 20Hz groups had improved significantly in terms of average bladder capacity, bladder pressure, residual urine volume, daily number of urethral catheterizations, daily micturition frequency, single urine output, H-reflex latency, and the amplitude and incubation period of the F wave. Those in the sham stimulation group showed no consistent improvement in any of these indicators. Moreover, the average residual urine volume, daily urination frequency and H-reflex latency and amplitude of the 20Hz group were significantly better than those of the 5Hz group.Conclusions:Magnetic stimulation of the S3 nerve roots can effectively improve the urination of persons with neurogenic bladder disorders after a spinal cord injury. The preferred frequency is 20Hz.
ABSTRACT
OBJECTIVES@#Electroacupuncture can enhance autophagic flow, promote neuronal regeneration, axonal and myelin remodeling to achieve the protection of spinal cord injury, but its role in neurogenic urine retention is not completely clear. This study aims to investigate whether the mechanism of electroacupuncture in the treatment of neurogenic urine retention is through autophagy mediated by adenosine monophosphate activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway.@*METHODS@#A rat model of neurogenic urine retention after sacral spinal cord injury was established. The rats with successful model were randomly divided into a model group, an electroacupuncture group (electro-acupuncture for Ciliao, Zhongji, and Sanyinjiao by electronic stimulation, once a day, 20 min each time for 7 days), and an electroacupuncture+AMP-activated protein kinase (AMPK) inhibitor group (on the basis of the treatment of electroacupuncture group, 100 μg of AMPK inhibitor compound C was injected intramuscularly around the L2-3 intervertebral space on the 1st and 4th day). The normal group did not receive any treatment. The maximum bladder volume, bladder basal pressure, leak point pressure, and bladder compliance were recorded by multi-channel physiological recorder; the morphology of bladder tissue was observed by HE staining; autophagy was observed under transmission electron microscope; the expressions of LC3II and Beclin1 protein were observed by immunofluorescence staining; the protein levels of AMPK, phosphorylated-AMPK (p-AMPK), mTOR, phosphorylated-mTOR (p-mTOR), microtubule associated protein 1 light chain 3 (LC3) II and Beclin1 in bladder tissue were detected by Western blotting.@*RESULTS@#Compared with the normal group, the maximum bladder capacity, leak point pressure, bladder compliance, p-AMPK, LC3II, Beclin1 protein expressions in the bladder tissue of the model group increased, and the p-mTOR protein expressions were decreased (all P<0.05); compared with the model group, the maximum bladder capacity, bladder compliance, p-mTOR protein expression in the bladder tissue of the electroacupuncture group were decreased, and the p-AMPK, LC3II, and Beclin1 protein expressions were increased (all P<0.05); compared with the electroacupuncture group, the maximum bladder capacity, bladder compliance, p-mTOR protein expression in the bladder tissue of the electroacupuncture+AMPK inhibitor group were increased, the p-AMPK, LC3II, and Beclin1 protein expressions were decreased (all P<0.05). In the model group, the bladder became larger, with unclear and varying degrees of degeneration, severe tissue damage and autophagosome appeared; the bladder of the electroacupuncture group was smaller than that of the model group, and all levels were clearly visible with autophagy bodies; the layers were slightly disordered and damaged in the electroacupuncture + AMPK inhibitor group.@*CONCLUSIONS@#Electroacupuncture can activate autophagy through AMPK/mTOR pathway, thereby reducing neurogenic urine retention caused by spinal cord injury.

The puerperal hematoma corresponds to a tissue cleavage, most often paravaginal or vulvar, in which the vascular wounds, linked to the detachment, have no spontaneous tendency to haemostasis. The aggravation of this pathology is progressive. Diagnosis and management must be an obstetric emergency. Author report a case of infected puerperal hematoma complicated by rectal compression and acute retention of urine. This is a 26-year-old patient with a history of chronic hypertension. Labor was induced by misoprostol. The delivery was uneventful at 37 weeks vaginally. Ten days after delivery, she returned to the obstetrical emergency service for acute urine retention. The examination with the vaginal speculum showed a tumefaction of six centimeters on the left lateral side of the vagina. Surgical treatment has been performed. The suite was without particularity. The diagnosis of puerperal hematoma must be early. Even for the delayed form, the complications are identical. Blood loss, compression of proximity organs and infection are the most common complications. The care must be multidisciplinary. Resuscitation of the patient associated with haemostasis of the vessel is the main treatment in cases of large hematoma with hemodynamic instability.
ABSTRACT
Objective To investigate the effect of spontaneous urination training on postoperative urine retention and catheteration duration of cervical cancer patients. Methods Seventy patients were divided into the control group (n=34) and control group(n=36). according to the admission time Both groups received bladder function training. Besides this, the control group also received intermittent clamping of urine catheter while the observation group received spontaneous urination training . The two groups were compared in terms of incidence of urinary retention and catheteration duration. Result The incidence of urinary retention in the observation group was lower than that of the control group, there was significant difference between the this groups (P<0.05). Conclusion For the patients after cervical cancer operation , both bladder function training and urination training can reduce the incidence of urine retention .
ABSTRACT
Objective To investigate the effectiveness of botulinum toxin A (BTX-A) injection to the external urethral sphincter guided by ultrasound in the treatment of various types of lower urinary tract dysfunction.Methods Twenty-two patients with urinary retention caused by neurological dysfunction (neurogenic bladder) were recruited,of which 18 were men and 4 women.They had various types of lower urinary tract dysfunction including detrusor external sphincter dyssynergia (DESD) in 7,nonrelaxing urethral sphincters in 5,and detrusor underactivity in 10.BTX-A (100 U) was injected into the external urethral sphincter at three different points guided by ultrasound.Clinical effects and urodynamic parameters were compared at baseline and after treatment.Results After treatment the urinary function and urodynamic parameters in each group improved significantly compared with the baseline.Maximum efficacy was observed at the 4th week.In the DESD group,3 patients (43％) had an excellent result and 3 (43％) had significant improvement; in the nonrelaxing sphincter group 3 (60％) had excellent results and 2 (40％) showed significant improvement; in the detrusor underactivity group 5 (50％) had excellent results and 3 (30％) had significant improvement.There were no obvious side effects.Conclusions BTX-A injections guided by ultrasound can accurately locate the external urethral sphincter.It is a simple and repeatable method for the treatment of lower urinary tract dysfunction.
