    Input: Introduction 0.05 % betamethasone valerate cream is generally used as an alternative to circumcision for the treatment of phimosis in boys . The aim of this study is to determine whether the half-strength formula ( 0.025 % ) of betamethasone is as effective as 0.05 % betamethasone . Method All boys with phimosis seen at our institution between 2010 and 2012 , whose parents complained that their children had problems of micturition , i.e. , crying and ballooning , and sought for some instructions or treatments , were instructed to apply betamethasone valerate cream . Two strengths , 0.05 and 0.025 % , were r and omly applied to each patient twice a day for 2 months . The patients whose parents were not willing to the conservative treatment underwent circumcision . Results Of the 47 patients , 23 boys with an average age of 16.65 ± 4.052 months ( range 11–24 months ) were given 0.025 % betamethasone cream , whereas the remaining 24 boys in control group with an average age of 18.42 ± 5.030 months ( range 10–24 months ) were instructed to apply with 0.05 % betamethasone valerate cream . Using unpaired t test , the age in both groups were comparable ( p = 0.1932 ) . There was a decrease in phimosis grade by the end of the therapeutic course in both groups . Further analysis using Mann – Whitney test revealed that the phimosis grade in the half-strength group ( 0.025 % strength ) was significantly lower to the phimosis grade in the control ( 0.05 % betamethasone ) group ( p = 0.0003 ) . There was no diversion from steroid application to circumcision or any side effects in the both groups . Conclusions 0.025 % betamethasone valerate cream produced a clinical improvement . However , the half-strength formula was not effective as the conventional formula of 0.05 % betamethasone valerate cream PURPOSE To compare the efficacy of three different formulations containing Betamethasone Valerate versus placebo in the topical treatment of phimosis . As a secondary goal , we compared the outcomes after 30 and 60 days of treatment . MATERIAL S AND METHODS Two hundred twenty boys aged 3 to 10 years old with clinical diagnosis of phimosis were enrolled . Patients were r and omized to one of the following groups : Group 1 : Betamethasone Valerate 0.2 % plus Hyaluronidase ; Group 2 : Betamethasone Valerate 0.2 % ; Group 3 : Betamethasone Valerate 0.1 % or Group 4 : placebo . Parents were instructed to apply the formula twice a day for 60 days and follow-up evaluations were scheduled at 30 , 60 and 240 days after the first consultation . Success was defined as complete and easy foreskin retraction . RESULTS One hundred ninety-five patients were included at our final analysis . Group 1 ( N = 54 ) , 2 ( N = 51 ) and 3 ( N = 52 ) had similar success and improvement rates , all treatment groups had higher success rates than placebo ( N = 38 ) . After 60 days of treatment , total and partial response rates for Groups 1 , 2 and 3 were 54.8 % and 40.1 % , respectively , while placebo had a success rate of 29 % . Success and improvement rates were significantly better in 60 days when compared to 30 days . CONCLUSIONS Betamethasone Valerate 0.1 % , 0.2 % and 0.2 % in combination with Hyaluronidase had equally higher results than placebo in the treatment of phimosis in boys from three to ten years-old . Patients initially with partial or no response can reach complete response after 60 days of treatment PURPOSE To compare the efficacy and costs of circumcision versus topical treatment using a prospect i ve pharmacoeconomic protocol . MATERIAL S AND METHODS We treated 59 patients ( 3 - 10 years of age ) r and omized into two groups : 29 underwent an 8-week course of topical treatment with 0.2 % betamethasone-hyaluronidase cream twice a day ; and 30 underwent circumcision .  Topical treatment success was defined as complete exposure of the glans . In cases of treatment failure , circumcision was performed and its cost imputed to that of the initial treatment . The pharmacoeconomic aspects were defined according to the Brazilian National Public Health System data base and the Brazilian Community Pharmacies Index . RESULTS The two groups were statistically similar for all clinical parameters evaluated . Topical treatment result ed in complete exposure of the glans in 52 % of the patients . Topical treatment was associated with preputial pain and hyperemia . However , treatment suspension was unnecessary . Minor complications were observed in 16.6 % of the surgical group patients . The mean cost per patient was US$ 53.70 and US$ 125.20 , respectively , for topical steroid treatment ( including the costs related to treatment failure ) and circumcision . The total costs were US$ 2,825.32 and US$ 3,885.73 for topical treatment and circumcision , respectively . CONCLUSIONS Topical treatment of phimosis can reduce costs by 27.3 % in comparison with circumcision . Therefore , topical treatment of phimosis should be considered prior to the decision to perform surgery Objectives Topical steroids have been advocated as an effective alternative treatment to circumcision in boys with phimosis . We evaluated the effectiveness of topical steroid therapy compared to a placebo neutral cream in 240 patients with phimosis . Methods A prospect i ve study was carried out over a 24-months period , on an out-patient basis on two groups of patients with phimosis . One-hundred twenty patients applied a steroid cream twice a day for 4 weeks , and another group of 120 pts used a placebo cream twice a day for 4 weeks . Patients were assigned to either group by a computer-generated r and om choice . Results All patients in our series completed the two treatment periods without interruption . At a median follow-up of 20 months ( 6–30 months ) therapeutic success was obtained in 43.75 % ( 99/240 ) of cases , independently of the protocol . In particular , therapeutic success was obtained in 65.8 % ( 79/120 ) of cases in the steroids group and in 16.6 % ( 20/120 ) of cases in the placebo group , the difference being statistically significant ( P < 0.0001 , Mann – Withney test ) . Conclusion Our study shows that topical steroids represent a good alternative to surgery in case of phimosis . Steroid therapy using monometasone furoate 0.1 % in our series gave better results that placebo with an overall efficacy of 65.8 % . In patients where a phimotic ring persist after steroid therapy , circumcision is m and atory PURPOSE We report a prospect i ve r and omized study comparing the effects of highly potent and moderately potent topical steroids in treating pediatric phimosis . MATERIAL S AND METHODS A total of 70 boys 1 to 12 years old with phimosis were r and omly assigned to receive topical application of either betamethasone valerate 0.06 % ( a highly potent steroid ) or clobetasone butyrate 0.05 % ( a moderately potent steroid ) . Parents of the boys were instructed to retract the foreskin gently without causing pain , and to apply the topical steroids over the stenotic opening of the prepuce twice daily for 4 weeks , then for another 4 weeks if no improvement was achieved . Retractibility of the prepuce was grade d from 0 to 5 . Response to treatment was arbitrarily defined as improvement in the retractibility score of more than 2 points . RESULTS Mean treatment and followup periods were 4.3 and 19.1 weeks , respectively . The response rates in boys treated with betamethasone valerate and clobetasone butyrate were 81.3 % and 77.4 % , respectively ( p = 0.63 ) . Mean retractibility score decreased from 3.9 + /- 1.0 to 1.7 + /- 1.1 , and 4.2 + /- 1.0 to 1.9 + /- 1.0 in the betamethasone and clobetasone groups , respectively . Both steroids were effective in all age groups . Pretreatment retractibility score did not affect treatment outcomes . No adverse effect was encountered . CONCLUSIONS Highly potent and moderately potent topical steroids are of comparable effectiveness in treating phimosis . A less potent steroid may be considered first to decrease the risk of the potential adverse effects OBJECTIVE To further test the application of topical steroids in boys referred to a paediatric surgical practice with pathological , non-retractable foreskins diagnosed as phimosis . PATIENTS AND METHODS This prospect i ve study comprised two groups of 20 boys each ( mean age 4.1 years , range 3 - 6 ) diagnosed as having phimosis ; twice daily , a topical steroid ( 0.05 % betamethasone cream ) was applied on the narrowed preputial skin in the first group and a neutral cream ( Vaseline ) in the second ( control ) group . Patients were treated for 4 weeks and the retractability of the foreskin and any side-effects assessed . RESULTS Good retraction of the foreskin was achieved in 19 patients treated with betamethasone cream and the response was unsatisfactory in 16 patients from the control group ; these 16 boys and one 6-year-old boy treated with betamethasone were circumsized . There were no side-effects or problems after the application of either cream . CONCLUSION Treatment with 0.05 % betamethasone cream is a simple and safe method for the treatment of phimosis in boys older than 3 years . An early operation is necessary in cases of genuine phimosis when 1 month of treatment with topical steroids has failed . We strongly support the saying , " The fortunate foreskin of an infant boy will usually be left well alone by everyone but its owner ' PURPOSE Between 2 % and 5 % of uncircumcised boys have persistent or pathological phimosis . Traditional treatment is usually circumcision . Recently medical treatment with topical corticosteroids has become more popular . We evaluated the efficacy of the topical steroid triamcinolone compared to foreskin retraction with an emollient cream and verified the long-term success rate of these treatments . MATERIAL S AND METHODS We performed a double-blind , r and omized , placebo controlled study to compare 2-month twice daily treatment with emollient cream ( placebo group 1 ) vs 0.1 % triamcinolone ( experimental group 2 ) . Boys between ages 3 and 12 years with persistent or pathological phimosis were included in analysis . Study EXCLUSION criteria were previous treatment with topical corticosteroid , untreated balanitis and any known medical condition with immune system impairment . Patients were seen 2 , 4 and 12 months after treatment initiation . Success was defined as complete , easy foreskin retraction at 4 and 12 months . Statistical analysis was done using Fisher 's exact test . RESULTS We enrolled 63 patients , of whom 43 completed the study . Despite multiple attempts 20 patients had incomplete followup and were excluded from study . Placebo group 1 included 25 patients and triamcinolone group 2 included 21 . In group 1 the success rate was significantly lower than in group 2 ( 9 patients or 39 % vs 16 or 76 % , p = 0.0086 ) . At 2 months 5 and 16 nonresponders in groups 2 and 1 , respectively , were treated in nonblinded fashion with topical triamcinolone . In this subgroup 1 of 3 group 2 patients and 6 of 13 in group 1 achieved complete , easy retraction . Two and 1 patients were lost to followup in groups 1 and 2 , respectively . Circumcision was required in only 5 patients ( 11.6 % ) , including 4 ( 17.4 % ) initially in group 1 . No complications were noted in either group . CONCLUSIONS Triamcinolone is a highly effective and safe short-term treatment for persistent physiological or pathological phimosis . However , at long-term followup recurrence is frequent and not rare with triamcinolone and it may require re-treatment or circumcision The effect of hydrocortisone ( HC ) , the steroid of lowest potency , and physiotherapy ( PT ) on non-retractile physiologic phimosis ( PP ) and the reduction of subsequent recurrent UTI was evaluated in male infants with UTI . Seventy-eight male infants with febrile UTI and nonretractile PP were prospect ively r and omized into HC ( Plancol , n=39 ) and control ( Vaseline , n=39 ) groups . Topical application of HC as a thin film around the preputial margin twice a day for four weeks with PT was instructed . The response rate in the HC group was 89.7 % ( 35/39 ) , which was significantly higher than the rate ( 20.5 % ; 8/39 ) in the control group ( P<0.05 ) . In the HC group , the response rate was much higher ( 96.1 % ) in the subgroup with PT than in the group without PT . Most of the response ( 88.5 % ) was observed within two weeks . During the following year , the recurrent rate of UTI was 7.1 % ( 2/28 ) in the infants with ret

Topical corticosteroids offer an effective alternative for treating phimosis in boys .
Although sub optimal reporting among the included studies meant that the size of the effect remains uncertain , corticosteroids appear to be a safe , less invasive first-line treatment option before undertaking surgery to correct phimosis in boys
