How Does the COVID-19 Pandemic Affect Pediatric Patients with Intussusception Treated by Ultrasound-Guided Hydrostatic Enema Reduction?

Background: The pandemic of COVID-19 has significantly influenced the epidemiology of intussusception. Nevertheless, the effects of the COVID-19 pandemic on the operation of ultrasound-guided hydrostatic enema reduction (USGHER) for intussusception have been largely unknown.

Methods: The data of pediatric patients with intussusception who were treated by USGHER from January to March of 2019 (Control Group), 2020 (Study Group 1), and 2021 (Study Group 2) in a large Chinese medical institution were retrospectively collected and analyzed.

[Ultrasonic Manifestations of Desmoplastic Small Round Cell Tumor with Multiple Metastases: Case Report].

Desmoplastic small round cell tumor (DSRCT) is a rare malignant tumor, which is prone to occur in teenagers DSRCT is a rare malignant tumor that often occurs in adolescents. Early diagnosis is difficult and the prognosis is poor. In this case report, the ultrasonography of DSRCT showed that the huge solid mass was in the abdomen with unclear boundary, irregular shape, insufficient blood supply but without obvious liquefaction and calcification.

A rare content of congenital inguinal hernia: a case report of splenogonadal fusion.

Background: Splenogonadal fusion (SGF) is a rare congenital malformation that occurs during embryonic development. SGF typically presents as a left-sided scrotal swelling, left inguinal hernia, scrotal mass, or cryptorchidism. Therefore, it is easily misdiagnosed, and unnecessary orchiectomy may occur.

[Ultrasound Manifestations of Eyes of Pediatric Patients with Morning Glory Syndrome].

Objective: To analyze ultrasonic manifestations of eyes of pediatric patients with morning glory syndrome (MGS).

Methods: Clinical data and ultrasound (US) findings for six children (4 males and 2 females, 5-60 months old) diagnosed with MGS between 2005 and 2016 were reviewed.

Results: Of the 12 eyes, seven were diagnosed with MGS; one with cataract; the other four were normal.

Ultrasound in diagnosis of intrascrotal metastasis of Wilms' tumor: first case report of a Chinese boy and review of the literature.

A 31-month-old boy with Wilms' tumor (WT), which primarily had originated from the left kidney, was treated with nephrectomy and adjuvant chemotherapy. 2 months after nephrectomy, a left scrotal mass was found at routine follow-up. High-frequency sonography examination revealed an enlarged left testis with a heterogeneous texture and a hypoechoic solid mass in the left scrotum.

The effect of CO2 pneumovesicum on upper urinary tract.

Objective: Pneumovesicum allows minimal invasive intravesical surgeries. The possible deleterious effect of intravesical CO(2) pressure is not known. We assessed the effect of CO(2) pneumovesicum on the urinary tract and renal function.

Dynamic ultrasound study on urinary bladder in infants with antenatally detected fetal hydronephrosis.

To evaluate bladder function in infants with antenatally diagnosed hydronephrosis (ANH) using dynamic ultrasound protocol. Forty consecutive male infants (mean, 0.25 y) with ANH and 33 age-matched normal controls (mean, 0.

[Alteration of bladder function in response to surgical reduction in bladder capacity: conventional-fill cystometry in awake rabbit model].

Objective: To investigate alteration of bladder function in response to surgically reduced bladder capacity by using an awake rabbit model.

Methods: Forty rabbits were divided into two groups, one was experimental group in which the rabbits underwent semi-cystectomy to reduce 50% bladder capacity (n=20), another was control group in which the rabbits received sham operation (n=20). A conventional-fill cystometric investigation was performed as the animal under awake condition at the times of 4 weeks and 8 weeks after operation.

[The labral plicae entrapment syndrome of hip in children: an ultrasonography study].

Objective: To study the ultrasonographic (US) features of labral plicae entrapment syndrome of hip (LPEH) in children and to evaluate the value of US in diagnosing LPEH.

Methods: (1) Twenty six LPEH models and 38 sham LPEH hips were established surgically from 32 children cadavers [15 male and 17 female, age from 2 to 8 years, mean age of (6.12 +/- 2.
