ISLAM, Reajul et al. Gross Anatomy of Urethra and Penis in Uncastrated and Castrated Buck of Black Bengal Goat. Int. J. Morphol. [online]. 2021, vol.39, n.1, pp.138-142. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022021000100138.

Urethral process, sigmoid flexure, urethra at the pelvic arch and neck of urinary bladder in goats are very much prone to form obstructive urolithiasis. The present study was carried out to establish baseline work on the normal measurement of the urethral passage and different segments of penis of uncastrated and castrated Black Bengal (BB) goat which will be supportive for obstructive urolithiasis management. Different segment of penis along with urethra of 25 uncastrated and 25 castrated male Black Bengal goats were collected from different slaughter house of Chattogram City Corporation. The length and diameter of male urethra and different segment of penis in uncastrated buck were significantly higher (p<.001) than castrated buck. The length of the pelvic urethra was 5.88 ± 0.111 cm and 4.58 ± 0.15 cm in uncastrated and castrated buck respectively. The length of the neck of urinary bladder; root, body, sigmoid flexure, glans penis and urethral process of the penis in uncastrated and castrated buck were 0.688 ± 0.156 cm and 0.38 ± 0.048 cm, 5.02 ± 0.09 cm and 4.24±0.10 cm, 23.48 ± 0.37 cm and 22.74 ± 0.43 cm, 9.2 ± 0.107 cm and 8.18 ± 0.29 cm, 1.92 ± 0.032 cm and 1.44 ± 0.10 cm, 2.32 ± 0.029 cm and 1.78 ± 0.07 cm respectively. The diameter of the neck of urinary bladder, root, body, sigmoid flexure, glans penis and urethral process of the penis in uncastrated and castrated buck were 1.94 ± 0.041 cm and 1.44 ± 0.05 cm, 3.7 ± 0.049 cm and 3.3 ± 0.144 cm, 2.63 ± 0.066 cm and 1.86 ± 0.08 cm, 2.77 ± 0.90 cm and 2.18 ± 0.07 cm , 1.81 ± 0.034 cm and 1.4 ± 0.06 cm, 0.66 ± 0.014 cm and 0.56 ± 0.05 cm respectively. Finally, total lengths of penis in uncastrated and castrated buck were 30.42±0.459 cm and 28.42±0.553 cm respectively. The length and diameter of the neck of the urinary bladder, root, sigmoid flexure, urethral process of the penis are clinically more important for obstructive urolithiasis.
