TUJUANMenilai perubahan pancaran urin maksimal (Amax) pada penderita striktur uretra setelah uretrotomi interna dan hubungannya dengan letak dan panjang striktur uretra.BAHAN DAN CARAPenelitian ini dilakukan secara deskriptif korelatif ( cross-sectional study ). Penelitian ini dilakukan dengan pemeriksaan Q max pada penderita striktur uretra setelah kateter uretra dilepas dan tiga minggu pasca uretrotomi intema di poliklinik bagian bedah urologi RSVP Dr. Hasan Sadikin Bandung selama periode Desember 2001-November 2002. Dilakukan analisa statistik dengan uji Mann-Whitney.HASIL PENELITIANDidapatkan 61 penderita striktur uretra pasca uretrotomi intema dengan 41 penderita (67,2%) panjang striktur uretra ≤ 2 cm dan 47 penderita (77%) striktur uretra anterior.

OBJECTIVESThe aim of this study is to assess the changes in Q max of patients with urethral stricture after internal urethrotomy regarding the correlation with the location and the length of the stricture.METHODSA prospective cross-sectional observation was conducted to evaluate the correlation between Q max and the length as well as the location of stricture. The Q max obtained after urethral catheter removal were compared to the Q max three weeks after the procedures. The length and the locations of the stricture were evaluated using retrograde as well as antegrade uretrography. The study was conducted in OPD of Hasan Sadikin Hospital Bandung between December 2001 - November 2002. Statistical analysis used was Mann-Whitney test. RESULTSFourty-one patients (67.2%) out of 61 patients with urethral stricture underwent internal urethrotomy have a stricture ≤ 2 cm in length while 47 patients (77%) have a stricture in the anterior part of the urethra Q maxAfter urethral Catheter RemovalRemoval Q maxThree Weeks After InternaLength of stricture < 10 ml/s ≥10 ml/s < l0 ml/s ≥10 ml/s≤ 2crn 12,2 % 87,8 % 48,7 % 51,3 %> 2cm 35% 65% 75% 25%Location of Stricture Anterior 19,1 % 80,9 % 55,6 % 44,4 %Posterior 21,4 % 78,6 % 71,4 % 28,6 %There is a significant correlation between the length of the stricture and Q max ( p = 0.012 ) but the correlation between the location of the stricture and Q max is not significant.CONCLUSIONSThe changes of Q max after internal urethrotomy are influenced by the length of the stricture but not by the location of the stricture.
