Tipe hipospadia proksimal merupakan faktor risiko pancaran urin yang lemah pada pasien hipospadia pasca uretroplasti teknik tubularized incised plate

ABSTRACT Hypospadias is the second most frequent congenital anomali on male. It characterized by a meatus that opens into the ventral surface of penis. According to its meatus location, there are two groups of classification: proximal and distal hypospadias. Surgery is the only modality of therapy, whereas the aim are to restore functional and cosmetical physiology. The most widespread operative technique used is Tubularized Incised Plate (TIP) by Snodgrass. This technique usually used to correct distal hypospadias but nowdays began as the alternative method for proximal hypospadias. Proximal type hypospadias has more difficulty level of reconstruction compare with the distal type. Weak urinary stream is one of complications from hypospadias surgery. The aim of this study is to prove whether proximal hypospadias type is a risk factor for weak urinary stream in hypospadias patient underwent TIP urethroplasty. This is a case-control study using 40 subject, 20 subject each group. Subject consisted of hypospadias patients who undergone operation at Sanglah hospital during January 2012 until December 2015 that matched with the inclusion criterias. We perform Qmax measurement to all this patients and the result then compared with the normal Qmax poin (> 10 ml/second). The result shows median Qmax are 9,54 ml/s and 22,49 ml/s for case and control group respectively. On the case group (Qmax ? 10 ml/second), 16 from 20 subjects have proximal type hypospadias, with OR is 16 (Cl 2,8-101; p 0,001). This result shows that proximal type of hypospadias is an important risk factor of weak urinary stream in patients post uretroplasty with TIP technique.
