ABSTRACT
OBJECTIVE: We aimed to compare the incidence of ureteric strictures between holmium:yttrium aluminum garnet and thulium fiber laser following ureteroscopic laser lithotripsy. In the present era of miniaturization of endourologic armamentarium and better optics, how safe are lasers to fire inside ureter? MATERIALS AND METHODS: It is a prospective comparative study over a period of 2 years that included patients who underwent ureteroscopic laser lithotripsy for ureteric stones. Patients were randomly divided into 2 groups: group A underwent holmium:yttrium aluminum garnet laser lithotripsy and group B underwent thulium fiber laser lithotripsy. RESULTS: A total of 478 patients were analyzed after excluding patients not willing to participate and patients lost to follow-up. Two hundred forty patients underwent holmium:yttrium aluminum garnet laser lithotripsy (group A) and 238 patients underwent thulium fiber laser lithotripsy (group B). The demographic data of 2 groups were comparable. The mean age of patients in group A and group B was 36.5 ± 12.52 years and 38.62 ± 10.71 years, respectively. The mean operative time in group A and group B was 47 ± 15 and 36 ± 13 minutes, respectively, while the mean laser time in group A and group B was 13.5 ± 45 minutes and 9.25 ± 3.2 minutes, respectively. Four (1.67%) patients in group A and 11 (4.62%) patients in group B developed ureteric strictures during follow-up, and the difference was statistically significant (P <.001). The mean length of stricture was 2.67 ± 1.27 cm in group A and 4.42 ± 2.2 cm in group B, and the difference was statistically significant. CONCLUSION: Thulium fiber laser, projected as safe laser previously, has a higher incidence of ureteric strictures compared to holmium:yttrium aluminum garnet laser when used for ureteroscopic laser lithotripsy.
ABSTRACT
Percutaneous nephrolithotomy is usually considered as safe and effective in the management of renal stones in pediatric population. Urinothorax defined as presence of urine in pleural cavity is a rare complication of percutaneous nephrolithotomy. We present a rare case of slowly developing urinothorax in a 9-year-old boy following PCNL due to migration of DJ stent into the pleural cavity. The case was managed by intracostal tube drainage and repositioning of DJ stent.
ABSTRACT
Spontaneous renal artery thrombosis is a rare medical emergency. The signs and symptoms of the disease are variable and non specific making it difficult to diagnose on time and easily missed for other more common pathologies. Proper evaluation and timely intervention can prevent the loss of renal function. We present a case of 45 year old male with no comorbidity who presented with complaints of right flank pain, fever and vomiting for one day. With physical examination within normal limits, evaluation revealed right renal artery thrombosis.
ABSTRACT
Sequestrum formation is a known complication of osteomyelitis. This is usually a source of chronic non resolving infection and inflammation. We present a rare case of pelvic sequestrum following septic arthritis of hip joint invading into the urinary bladder mimicking a bladder calculus and leading to hydroureteronephrosis.
