Article Synopsis
  • Retrograde intrarenal surgery (RIRS) is increasingly used to treat renal stone disease in children, but stone-free rates vary, and there's limited data on how long it takes to achieve this status.
  • A study evaluated 105 children who underwent RIRS, revealing that 42.2% achieved stone-free status after one procedure, while 75.5% reached this status within an average of 12.25 months, with variations based on stone types.
  • The findings emphasize the importance of long-term follow-up for pediatric patients after RIRS, as achieving a stone-free status can take over a year.

Background: Authors widely use pulse oximetry in clinical monitoring of heart rate (HR) and peripheral oxygen saturation (SpO2) by attachment to the fingers; however, there can be a need for an alternative attachment site, especially for burned patients. We investigate the availability of a pulse oximeter probe attached to the penile shaft as an alternative site in pediatric male patients if all extremities became unavailable for pulse oximetry measurement due to severe burn and/or trauma.

Methods: We designed a prospective comparative study in a training and research hospital.

Purpose: The most important point in cases of ureteropelvic junction obstruction (UPJO) is to decide on the need and timing of surgical treatment. Renal damage may become irreversible as the duration of the obstruction is prolonged. Worsening of hydronephrosis and decrease in renal parenchymal thickness after pyeloplasty may herald an irreversible renal damage.

Introduction: Multidrug resistance among bacteria increases the need for new therapeutic options. Tigecycline is one candidate drug, due to property of a wider anti-bacterial spectrum to multi-drug resistant (MDR) pathogens. However, it has still not been approved for use in pediatric patients.

Early or late posttransplant opportunistic infections are among the leading complications after liver transplant. The source of early posttransplant opportunistic infections is usually the patient, the implantation of an infected graft, contamination during a surgical procedure, or invasive interventions performed at the intensive care unit. A 10-year-old male patient with Wilson disease (Pediatric End-Stage Liver Disease Score of 42, Child-Pugh score of 12, total bilirubin 40 mg/dL, platelet count 55000/mL, hemoglobin level 6.

Partite patella is a known cause of anterior knee pain, especially in adolescents and young males, although most patients are asymptomatic. Symptomatic partite patella is usually revealed on magnetic resonance imaging (MRI) as bone marrow edema within the opposing bone fragments. We present a case of unusual bilateral symptomatic multipartite patella in an adult who presented with quadriceps fat pad edema and mass effect as well as slightly edematous signal changes within the bone fragments on MRI.
