RESUMO
OBJECTIVE: To assess prospectively the natural history and long-term testicular growth of acquired undescended testis (UDT) after spontaneous descent or pubertal orchidopexy in case of nondescent. PATIENTS AND METHODS: From 1996 until 2008, 391 boys with 464 acquired UDT were included in the study. In accordance with Dutch consensus on non-scrotal testes, spontaneous descent at puberty was awaited; if this did not take place, orchidopexy was performed at puberty. Acquired UDT was defined as a testis previously residing in the scrotum that can no longer be manipulated into a stable scrotal (high scrotal) or nonscrotal (inguinal, impalpable) position. After referral, testis position, testis volume and puberty stage were monitored annually until adolescence. Testis volume was assessed using an orchidometer and compared with the Dutch standard. All investigations were carried out by the same physician (W.H.). Of these boys, 84 (mean age 12.9 years, range 6.4-21.3) were also clinically assessed by a second physician (J.G.), unaware of the results of the first examination. In addition, these boys were assessed with testicular ultrasonography, carried out by both physicians. RESULTS: Currently the mean (range) follow-up is 4.7 (0.1-12.0) years, and 253 acquired UDT have reached the scrotum. In 196 of these 253 cases (77.5%), there was spontaneous descent at puberty (mean age at descent 12.9 years, range 9.8-16.9); in the other 57 cases (22.5%), pubertal orchidopexy was required due to nondescent; five cases required orchidectomy. Of the 494 testis volume measurements after spontaneous descent, 458 (92.7%) were at ≥10th centile for age, of which 311 (63.0%) were ≥50th centile, and 107 (21.7%) ≥90th centile. After pubertal orchidopexy for nondescent, of the 85 measurements, 79 (92.9%) were at ≥10th centile, 53 (62.4%) ≥50th centile and 12 (14.1%) ≥90th centile. In unilateral cases, after spontaneous descent 174 of the 294 (59.2%) retained testes were found to be smaller than their counterpart and 90 of 294 (30.6%) were equal in size. After pubertal orchidopexy in unilateral cases, 40 of the 51 (78.4%) testes were smaller, and nine (17.6%) were equal in size. There was a strong correlation between both investigators for the measurement of testicular volume by orchidometer, and for the main investigator (W.H.) between his measurements by ultrasonography and the Prader orchidometer. CONCLUSION: Acquired UDT has a 77.5% tendency of spontaneous descent at puberty. In nearly all cases, after spontaneous descent as well as after pubertal orchidopexy, long-term testicular growth is within the normal range.

PURPOSE: Intratesticular varicocele (ITV) is an uncommon sonographic finding. A prevalence of up to 2% has been reported in men with testicular problems. In a cohort of men who had undergone prepubertal orchidopexy for acquired undescended testis, several cases of ITV were found. The aim of this study was to analyse the prevalence and clinical aspects of ITV in this cohort. METHODS: In a long-term follow-up study of position and growth of undescended testis after prepubertal orchidopexy, ultrasonography was used to identify men with ITV. Data on clinical presentation, testicular volume, and the location, size and Doppler aspects of intratesticular varicocele were collected and analysed. RESULTS: Of the 105 men, 9 were identified with ITV (8.6%). In all patients, the side of orchidopexy correlated with the side of the ITV, and all were left-sided. The testis with ITV had a smaller volume than the testis without ITV (p = 0.026). CONCLUSIONS: A remarkably high prevalence of ITV (8.6%) was found as well as a smaller volume of the testes with ITV in a cohort of men who had undergone prepubertal orchidopexy for acquired undescended testis.

BACKGROUND: At present, the high scrotal testis is considered a distinct and separate entity of undescended testis. OBJECTIVES: The aim of this study was to assess whether high scrotal testis is actually either a congenital- or acquired-undescended testis. DISCUSSION: In 527 consecutive boys (aged 0.4 to 16.5 years, mean 7.5) referred for non-scrotal testis, the number of high scrotal testis was prospectively determined. According to previous testis position, the high scrotal testis was classified into congenital- and acquired-high scrotal testis. In congenital-high scrotal testis orchidopexy was performed whereas spontaneous descent at puberty was awaited in acquired-high scrotal testis. In 210 testes, the gonad was diagnosed as high scrotal. In six testes the condition was congenital and 204 testes were diagnosed as acquired. All cases of congenital-high scrotal testis were treated surgically. In 100 acquired-high scrotal testis follow-up was performed. Of these, 75 testes descended spontaneously at puberty. CONCLUSION: We propose that the high scrotal testis should be regarded, not as a distinct and separate entity, but as a part of the spectrum of either congenital-undescended testis or acquired-undescended testis. Since spontaneous descent can occur at puberty in acquired-high scrotal testis, therapy may be different between both forms.

PURPOSE: To present a case in which a covered stent fractured 7 months after implantation in the internal carotid artery (ICA). CASE REPORT: A 59-year-old man presented with a large traumatic pseudoaneurysm of the left ICA. Seven months after successful treatment with a covered Symbiot stent, clinical complaints recurred because the pseudoaneurysm recanalized due to fracture of the stent at its midsection. Surgical stent explantation was needed, with polytetrafluoroethylene graft reconstruction of the ICA. No complications occurred in the periprocedural period. A control duplex scan 12 months later showed exclusion of the pseudoaneurysm and no graft-related complications. CONCLUSIONS: This case demonstrates an as yet unreported complication of stent-grafting in a carotid artery.
