ABSTRACT
Pneumothorax is a rare complication in laparoscopic renal surgery. However, due to the increasing renal pathologies managed by laparoscopic technique, this infrequent complication is a potential risk. We investigated the incidence rate of this complication in our experience of laparoscopic renal surgery, taking into account the laparoscopic approach, the type of intervention, the character of the pathology (neoplastic or other), the site of the intervention, as well as the localization of the lesion (in case of malignant pathology). About 384 laparoscopic nephrectomies were reviewed at our institution, with a total of four cases (1.04%) of diaphragmatic injury. Diaphragmatic repair was always carried out by intracorporeal suturing, with no complications. Repair of diaphragmatic injuries should always be attempted with intracorporeal suture since this is a safe and effective technique. Then, although in the retroperitoneal approach pneumothorax is more likely, our experience has shown that transperitoneal access is not free from this complication.
ABSTRACT
The majority of testicular tumors are germ cell tumors (GCTs) which, although rare, frequently present in young adults. In exceptional circumstances, spontaneous regression of the primary tumor occurs. The appellation 'burned-out' is applied to situations in which a metastatic GCT is found to be present, accompanied by histological regression of the primary testicular lesion. It is of crucial importance that a clinical examination of the testis is performed, and scrotal sonography is essential in the preliminary diagnosis of such neoplasms. In the present case report, a burned-out, non-seminomatous testicular GCT case is described. A CT scan revealed that a 29-year-old male patient who was experiencing loss of weight and appetite had retroperitoneal and mediastinal masses. A testicular examination did not reveal the presence of any palpable lesion, and an ultrasound examination of the scrotum disclosed a normal left testis and an atrophic right testicle with heterogeneous architecture, but with no evidence of a tumor. Chemotherapy was administered to the patient following surgical intervention into the retroperitoneal and mediastinal mass. It is evident that it remains problematic to accurately differentiate between a primary retroperitoneal tumor and a metastatic testicular tumor with an occult testicular primary or a 'burned-out' testicular cancer. The burned-out phenomenon is a rare occurrence, and further research into its pathogenesis is required. Both the rarity of this phenomenon and the difficulties encountered in diagnosis prompted the writing of the present case report, especially considering that teratomas are categorized as belonging to the histology group that shows the least likelihood of regressing.
ABSTRACT
Patients with recurrent high grade and/or muscle-invasive bladder cancer and concomitant upper urinary tract disease, e.g. urothelial tumors or afunctional hydronephrotic kidneys, may be candidates for simultaneous laparoscopic cystectomy and nephroureterectomy. So, such patients, especially when affected by multiple comorbidities, can benefit from the avoidance of extended laparotomy. We report our experience with simultaneous laparoscopic radical cystectomy and right nephroureterectomy in a 67-year-old-male patient affected by recurrent polyfocal high grade bladder cancer and an associated right upper tract carcinoma. This laparoscopic approach was technically successful without the need for conversion to open surgery. More than a year after the surgery, the patient is still alive, showing no tumor relapse of at the established instrumental controls. This laparoscopic approach, performed in a single session, can be safe and feasible in selected cases as an alternative approach to the open surgery, offering good oncological and functional results.
ABSTRACT
Metastases to the penis from transitional cell carcinoma of the bladder are rare. In the literature about 300 cases of secondary penile malignancies were described; 35% out of these cases were from primary neoplasms of the bladder. The Authors describe a case of priapism secondary to penile metastases from a transitional cell carcinoma of the bladder.
