Two-stage orchiopexy with laparoscopic clip ligation of the spermatic vessels in prune-belly syndrome

Laparoscopy in the management of impalpable testis (Series of 64 Cases)

BACKGROUND

The undescended testis represents one of the most common disorders of childhood. Laparoscopy has been widely used both in the diagnosis and treatment of non-palpable testis. In this study, we investigated and evaluated the usefulness of laparoscopy in the diagnosis and treatment of no palpable testis.

PATIENTS AND METHODS

From January 2003 to January 2008, we used laparoscopy in the management of 64 patients with 75 impalpable testes. Their ages varied from 1 to 15 years (median age = 4.6 years). The site and the size of the testes were localised by abdominopelvic ultrasonography in all 64 children for accurate diagnosis. One stage laparoscopic orchiopexy was performed in 26 testes, staged Fowler-Stephens orchiopexy was underwent in 17 testes, while laparoscopic orchidectomy was done in 5 testes. Follow-up by clinical examination and colour Doppler ultrasound was performed in every patient who underwent orchiopexy.

RESULTS

There were 11 patients with bilateral non-palpable testes. The overall diagnostic agreement of ultrasound with laparoscopy was seen in only 16 out of 75 testes (21.3%). The results of diagnostic laparoscopy were varied and showed various pathological. Conditions and positioned of the testes, such as 20 low intra-abdominal testes (26.6%), 17 testes were high intra-abdominal (22.7%), and 18 testes (24%) entered the inguinal canal. Associated inguinal hernia was present in 4 patients. After a mean follow-up period of 26 months (6 months - 5 years), all testes were in the bottom of the scrotum except 3 testes were retracted to the neck of the scrotum and atrophy of the testis occurred in 2 patients (2.7%).

CONCLUSION

Laparoscopy has proven to be the only diagnostic modality where the findings provide a clear dependable direction for the definitive management of impalpable testes, so it allows an accurate diagnosis and definitive treatment in the same sitting.

Laparoscopy in the management of impalpable testis: series of 64 cases

BACKGROUND

The undescended testis represents one of the most common disorders of childhood. Laparoscopy has been widely used for the diagnosis and treatment of non-palpable testis. In this study, we investigated and evaluated the usefulness of laparoscopy in the diagnosis and treatment of the non-palpable testis.

METHODS

From January 2003 to January 2008, we used laparoscopy in the management of 64 patients with 75 impalpable testes. The patients' ages varied from 1 to 15 years (median 4.6 years). The sites and sizes of the testes were localized by abdominopelvic ultrasonography (US) in all 64 children. One-stage laparoscopic orchiopexy was performed for 26 testes, staged Fowler Stephens orchiopexy for 17 testes, and laparoscopic orchidectomy for five testes. Follow-up by clinical examination and color Doppler US was performed in every patient who underwent orchiopexy.

RESULTS

There were 11 patients with bilateral non-palpable testes. The overall diagnostic agreement of US with laparoscopy was seen for only 16 of 75 testes (21.3%). The results of diagnostic laparoscopy were varied and showed various pathologic conditions and positions of the testes, such as 20 low intraabdominal testes (26.6%), 17 high intraabdominal testes (22.7%), and 18 testes (24%) that had entered the inguinal canal. Associated inguinal hernia was present in four patients. After a mean follow-up period of 26 months (6 months-5 years) all testes were seen to be located in the bottom of the scrotum, with the exception of three testes that had retracted to the neck of the scrotum and two testes that had atrophied (2.7%).

CONCLUSIONS

Laparoscopy has proven to be the only diagnostic modality where the findings provide a clear, dependable direction for definitive management of impalpable testes. It allows an accurate diagnosis and simultaneous definitive treatment.

Unique Features of Prune Belly Syndrome in Laparoscopic Surgery

BACKGROUND

The aim of this study was to evaluate the laparoscopic abdominal access modifications in children with prune belly syndrome undergoing a first stage Fowler-Stephens procedure.

STUDY DESIGN

Eleven consecutive boys underwent a transperitoneal laparoscopic bilateral first stage Fowler-Stephens procedure. Patient age ranged from 1.5 to 3 years (mean age 2.2 years). In these patients, the floppy abdominal wall required a modified approach with regard to access technique, insufflation pressures, and work port stabilization methods. Duration of the procedures and intraoperative technical challenges encountered were prospectively documented.

RESULTS

Mean operative time was 40 minutes (range 30 to 75 minutes), and all procedures were completed without any complications. Forceful insertion of ports was not possible, and all ports were introduced under complete open access. Larger volumes of carbon dioxide were used in the initial part of our series, when the ports were not sutured to the abdominal wall. An abdominal pressure of 8 mmHg was maintained in all patients and was considered optimal for the procedures. Short laparoscopy instruments (240 mm) were unsuitable for the procedures and had to be replaced by longer instruments (310 mm or 430 mm).

CONCLUSIONS

Technical modifications are required to the approach in laparoscopic abdominal access to overcome the challenges posed by the floppy abdominal wall in prune belly patients. Open access, suture fixation of the optic and work ports, use of threaded sleeve ports, and use of proper length of laparoscopy instruments are valuable modifications to overcome the technical hurdles posed by these patients.

Initial management of complex pediatric disorders: prunebelly syndrome, posterior urethral valves

Prunebelly syndrome and posterior urethral valves are conditions of detrusor dysfunction associated with antenatal urethral obstruction. The resultant severe hydroureteronephrosis and renal dysplasia initiate a sequence potentially leading to renal failure. This article reviews clinical features and explores neonatal evaluation and treatment for both conditions. A comprehensive approach to initial management aimed at optimal renal preservation and bladder rehabilitation is proposed.
