ABSTRACT
Background: Epidermal inclusion cyst, smegma stones and urethral calculi of the penis are rare and may result as a late complication of hypospadias repair. This study reported the presentation and management of these late complications.Methods: A prospective observational study included male patients aged more than 6 years of age, who had undergone hypospadias repair 3-15 years back and presented with slow growing, non-tender, mobile, firm to hard swelling. Histopathological and radiographic examination were done and surgery was used for management of epidermal inclusion cyst, urethral calculi and smegma stone. Patients were followed up for one year, postoperatively.Results: Out of 15 patients, two (13.3%), four (26.7%) and nine (60%) patients were diagnosed with smegma stones, epidermal inclusion cyst and urethral calculi, respectively. The median (range) age of patients was 17 (8-30) years. Patients were presented with slow growing, non-tender, mobile swelling measuring from 1 cm x 3 cm to 2 cm x 1.5 cm. The average size of epidermal inclusion cyst, and urethral calculi was 2 cm x 2.5 cm x 1.5 cm, and 2 cm x 3 cm, respectively. Treatment were complete excision of cyst and removal of smegma stones by surgery and urethral calculi by dorsal urethrotomy. All patients had an uneventful postoperative period and were asymptomatic up to one year of follow-up.Conclusion: Results suggest that these complications can be managed with complete excision and surgical removal and care must be taken while performing the hypospadias repair to avoid these unusual late complications in patients.
ABSTRACT
Objective To evaluate the effect of EMS through ureteroscope per urethra for the treatment of infant bladder and urethral stone with acute urinary retention. Methods Ten cases (9 boys, 1 girl)of infant bladder and urethral stone with acute urinary retention were treated by EMS through ureteroscope per urethra. Mean age of the patients was 9 months. Two cases suffered from bladder stones while the other 8 cases suffered from urethral stones. The size of stones varied from 0.5-1.1 cm with the average of 0.8 cm. All 10 cases underwent EMS through ureteroseope per ure-thra after general anaesthesia by using ketamine in vein. Wolf F8/9. 8 ureteroscope was used and mo-nitored by television. The EMS probe of ultrasound lithotripsy was sticked through operating passway of ureteroscope to shatter and eliminate bladder and urethral stone. During operation, 50-- 100 ml li-quid pressure was retained in the urinary bladder. The pressure of perfusion pump varied between 160 and 210 kPa(average, 180 kPa). The energy of ultrasound lithotripsy was 40%--60% with a ratio of 30%--70%. F8 type of 2 cavity aerocyst urethral catheter was indwelled after operation. Results The average operation time was 25 min. Urethral stones were rinsed into bladder. Stones were elimi-nated at one time by ureteroscope. Urethral catheters were removed after the patients revived from anesthesia and smooth urination was seen immediately after operation. No retained calculus in the bladder and urethra was found by B ultrasound 3 days later. Conclusions Low urinary obstruction could be relieved immediately after EMS through ureteroscope per urethra in patients of infant bladder and urethral stone with acute urinary retention. This operation is safe, high-efficient with less lesion, and would be the first option for the patients of infant bladder and urethral stone with acute urinary re-tention.
ABSTRACT
Objective To treat urinary calculi with pneumatic lithotripsy under non-endoscopy.Methodes We applied the pneumatic lithotripsy machine,which made in China,to treat huge or staghom nephrolith and calculi of anterior urethra under non-endoscopy,taken out stone fragmentations after lithotripsy.There was 1 case of huge nephrolith,7cases of staghom nephrolith,3 cases of anterior urethral calculi.Results Every case of nephrolith was successfully performed by using lithotrisy and extracted stones only one case.1 case in total nephrolith cases was found residual stones and sick-side renal functions were improved than before in all casws followed up for 3 moths to 2 years.the cases of anterior urethral calculi urinated fluently and had no urethral stenoses followed up 1～2 years.Conclusion This kind of operation used pneumatic lithotripsy to treat urinary calculi under non-endoscopy is safe,slight injury and curative effect is reliable.
