The scan images of the normal bladder were obtained by intravesical ultrasonography (IVU) and the ultrasonographic-anatomic correlation were defined based on 179 procedures. Except in bladder cancer, IVU did not prove to be useful in the evaluation of other bladder conditions or adjacent structures, including gynecological disorders.
An experimental study with synadelpho-ureterostomy (transuretero-ureterostomy) was performed in 25 dogs. The conclusions reached are: (1) side-to-side anastomosis is to be preferred to end-to-side suture; (2) risk of disruption is very slight even where an unexpected obstruction is encountered (test with induced cellophanic periureteritis), and (3) segmental replacement of the lumbo-iliac ureter may apparently be achieved by means of inverted synadelpho-ureterostomy (the damaged ureter is the recipient ureter). This replacement requires a double synadelphostomy, but in our study the normal transposed ureter suffered no harm despite the presence of previous infection and ureteral dilatation.
Funiculus liposarcoma is a very uncommon tumor. Most cases have a low degree of malignancy. Inguinal orchiectomy with a wide local excision is the appropriate treatment. Liposarcoma presurgical diagnosis is very infrequent and ultrasonography is the method that can provide some help to locate it. Currently, chemotherapy indication is unclear. Due to recurrence, specially of local foci, being a possibility a periodical follow-up is necessary in these patients. Nowadays, local recurrences are treated with repeated ample local excisions and radiotherapy. This work reviews the literature and presents a new case of round cells liposarcoma of the funiculus.
Since the complications herewith presented as a consequence of surgical renal biopsy are really exceptional and references found in the existing literature rare, we have considered that the contribution of these two cases which developed a pneumomediastinum-pneumoperitoneum and pneumocele prespectively during the immediate post-surgical period would be of interest. Evolution was favourable in both cases, with spontaneous resolution of the process.
