Urinary calculi are the most easily formed stones in human body, which can lead to different degrees of urinary tract symptoms and seriously affect the quality of life of patients.

Objective: To explore the clinical diagnostic value of B-ultrasound in urinary calculi, and to provide reference for the clinical diagnosis and treatment of urinary calculi. Methods: Fifty-two patients with urinary calculi diagnosed in our hospital from June 20 13 to June 20 15 were selected as the research objects, and the diagnostic accuracy and imaging characteristics of urinary calculi diagnosed by B-ultrasound were analyzed. Results: Among 52 cases of urinary calculi, 25 cases (48.08%) were kidney calculi, which showed punctate or massive strong echo in the kidney with afterimage. 20 cases (38.46%) were ureterolithiasis, which showed that the stone echo was visible in the stagnant water, showing an enhanced arc light band, and the shadow was visible in the rear; 4 cases (7.69%) were bladder stones with strong echo and shadow in the triangle of bladder; There were 3 cases of posterior urethral calculi, accounting for 5.77%. Conclusion: The accuracy of B-ultrasound in the clinical diagnosis of urinary calculi is high, and it has high clinical application value.

Urinary calculi; B-ultrasound; diagnose

Urinary calculus is a common disease in general surgery, and its incidence has gradually increased in recent years. Timely and accurate diagnosis and scientific and effective treatment are of great significance to patients' health [1]. In this paper, the diagnosis results of 52 patients with urinary calculi diagnosed in our hospital from June 20 13 to June 20 15 were analyzed in order to provide reference for clinical diagnosis and treatment of urinary calculi. The report is as follows.

1 data and methods

1. 1 general information

Fifty-two patients with urinary calculi diagnosed in our hospital from June 20 13 to June 20 15 were selected as the research objects. All patients were diagnosed by B-ultrasound. The clinical manifestations are pain in one or both sides of the waist, hematuria, dysuria and bladder irritation. 23 patients had nausea and vomiting, 13 patients had collapse. There were 30 males and 22 females, aged from 30 to 55 years, with an average of (42.2? 1 1.2) years old; The course of disease is 3-9 years, with an average of (5.6? 2. 1) year.

1.2 method

52 cases were diagnosed by B-ultrasound, as follows: before examination, the patients were instructed to fill the bladder, and the position of stones was initially determined according to the clinical symptoms of the patients. For patients with upper ureteral calculi and kidney calculi, prone position should be taken, and patients with middle and lower ureteral calculi and bladder calculi should be taken in supine position. If necessary, the patient's body position can be adjusted appropriately according to the stone examination. The kidney, ureter and bladder of the patient were examined by B-ultrasound (Siemens G50 ultrasonic diagnostic instrument, curved linear probe, probe frequency 3.5MHz) in turn. Observe whether there are imaging features such as stones, hydronephrosis and ureteral dilatation at the exploration site. If ureterectasia is explored, it should be comprehensively explored from the upper end to the lower end.

1.3 observation index

The diagnosis results were analyzed, and the imaging characteristics of B-ultrasound in the diagnosis of urinary calculi were analyzed.

Two results

Among 52 cases of urinary calculi, 25 cases (48.08%) were kidney calculi, showing punctate or massive strong echo in the kidney with afterimage. 20 cases (38.46%) were ureterolithiasis, which showed that the stone echo was visible in the stagnant water, showing an enhanced arc light band, and the shadow was visible in the rear; 4 cases (7.69%) were bladder stones with strong echo and shadow in the triangle of bladder; There were 3 cases of posterior urethral calculi, accounting for 5.77%. The results of B-ultrasound diagnosis in 52 patients were analyzed. See table 1 for details.

3 discussion

Urinary calculi are the most easily formed stones in human body, which can lead to different degrees of urinary tract symptoms and seriously affect the quality of life of patients. B-ultrasound is the most widely used imaging diagnostic equipment in clinical diagnosis, which can be carried out by all primary medical institutions. For urinary calculi, B-ultrasound has shown good clinical application value, mainly because B-ultrasound diagnosis is not affected by stone components, and it has the advantages of rapidity, convenience and painless, and can also supplement the shortcomings of conventional X-ray diagnosis [2-3]. In this paper, 52 patients with urinary calculi were examined by B-ultrasound. Among them, there were 25 cases of kidney calculi (48.08%), 30 cases of ureteral calculi (38.46%), 4 cases of bladder calculi (7.69%) and 3 cases of posterior urethral calculi (5.77%), which were basically consistent with the research results of His et al.

In clinical diagnosis, special attention should be paid to the differential diagnosis of kidney calculi and ureteral calculi. Early diagnosis and scientific treatment are particularly important for alleviating patients' pain and improving clinical treatment effect. The results of this study show that bladder stones and posterior urethral stones are relatively few in all urinary calculi, which is related to the fewer cases in this group. On the other hand, Ma Lifen [5] also pointed out in related reports that the incidence of these two kinds of urinary calculi is low, so we should pay special attention to them in clinical diagnosis.

B-ultrasound diagnosis of kidney calculi is relatively simple. In this set of data, kidney calculi's B-mode ultrasound diagnosis is characterized by punctate or massive strong echo in the kidney, and the rear shadow can be seen. The echo spot is strong, the light mass is clear, and the diagnosis is clear.

Ureteral stones are mostly unilateral stones, so patients should be instructed to keep their bladder full before examination, because smaller stones should not lead to dilatation of renal pelvis and ureter. Under the condition of insufficient bladder filling, B-ultrasound may miss the diagnosis of lower ureteral calculi [6-8]. In addition, bladder stones and posterior urethral stones account for a small proportion in the incidence of urinary calculi.

The strong echo and shadow in the patient's bladder triangle can be used as an important basis for judging bladder stones, and bladder stones can move in the direction of gravity with the change of body position, which can also be used as a diagnostic basis for bladder stones, which is basically consistent with the research results in reference [9- 10], further indicating that B-ultrasound has a good diagnostic value for urinary calculi. To sum up, the accuracy of B-ultrasound in the clinical diagnosis of urinary calculi is high, and it is rapid, convenient and painless, and has high clinical application value.
