What's known on the subject? and What does the study add? The interest in metastatic renal cell carcinoma has increased in the last few years, mainly due to the advent of targeted therapies, but metastasectomy remains the sole therapy that can lead to a complete and durable regression, even if only in a minority of patients. The literature reports quite large series of metastasectomies for the most common sites of metastasis, e.g. lung, liver, bone, adrenal and brain, whereas little is known about the management of metastasis in 'atypical' sites. The prognosis of patients submitted to metastasectomy for a metastasis in an atypical site is equivalent to patients with lung metastasis. The characteristics of the primary tumour in these patients are not indicative, but atypical metastasis (AM) are often located in superficial sites and frequently associated with other metastases. So, physical examination should be included in all follow-up regimens and a complete re-staging should be performed after the diagnosis of an AM. ⋯ • AM are an exceptional presentation of metastatic RCC, but the role of surgery is similar to that of pulmonary metastasis. In these cases, metastasectomy is accepted as possible care, and in AM the CSS after metastasectomy is similar.

Comparative Study
Vasectomy reversal with ultrasonography-guided spermatic cord block.
Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Vasectomy reversal is often performed in general or neuraxial anaesthesia. Even though the site of vasectomy reversal is easily amenable to regional/local anaesthesia, spermatic cord blocks are rarely applied because of their risk of vascular damage within the spermatic cord. Recently, we described the technique of ultrasonography (US)-guided spermatic cord block for scrotal surgery, which, thanks to the US guidance, at the same time avoids the risk of vascular damage of blindly performed injections and the risks of general and neuraxial anaesthesia. Vasectomy reversal can easily be done in regional anaesthesia with the newly described technique of US-guided spermatic cord block without the risks of vascular damage by a blindly performed injection and the risks of standard general and neuraxial anaesthesia. In addition, this technique grants long-lasting postoperative pain relief and patients recover more quickly. Microsurgical conditions are excellent and patient satisfaction is high. Thanks to these advantages, more patients undergoing vasectomy reversal might avoid general or neuraxial anaesthesia. ⋯ • US-guided spermatic cord block for microscopic vasectomy reversal is highly successful and provides long-lasting perioperative analgesia. • Times to alimentation, mobilization and hospital discharge are shorter under US-guided spermatic cord block than under general/neuraxial anaesthesia. • Additional anaesthetic pain management might, however, be required unexpectedly with US-guided spermatic cord block.

Comparative Study
A new prognostic model for cancer-specific survival after radical cystectomy including pretreatment thrombocytosis and standard pathological risk factors.
Study Type - Prognosis (cohort series) Level of Evidence 2a What's known on the subject? and What does the study add? Preoperative thrombocytosis has been identified as a predictor of poor outcome in various cancer types. However, the prognostic role of platelet count in patients with invasive bladder cancer undergoing radical cystectomy is unknown. The present study demonstrates that preoperative thrombocytosis is an independent risk factor for decreased cancer-specific survival after radical treatment of invasive bladder cancer. We developed a new prognostic scoring model for cancer-specific outcomes after radical cystectomy including platelet count and established pathological risk factors. Consideration of platelet count in the final model increased its predictive accuracy significantly. Thrombocytosis may be a useful parameter to include within established international bladder cancer nomograms. ⋯ • The presence of thrombocytosis at radical cystectomy portends unfavourable prognosis. • We constructed a simple weighted prognostic model for cancer-specific outcomes after radical cystectomy based on pretreatment platelet count and established pathological risk factors. • These data warrant external validation and may allow for tailored monitoring and selection of appropriate patients for neoadjuvant and adjuvant trials.

Comparative Study
Towards bloodless cystectomy: a 10-year experience of intra-operative cell salvage during radical cystectomy.
Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Guidance from the UK National Institute for Health and Clinical Excellence (NICE) on the use of intraoperative cell savage (ICS) has been in place for over 3 years and recommends its routine usage in all patients undergoing radical pelvic urological surgery. The current series describes the contribution of ICS to contemporary blood conservation strategies and the goal of 'bloodless' cystectomy. ⋯ • In conclusion, the use of ICS during radical cystectomy is safe; it is capable of meeting the majority of or, in some cases, the total blood product requirement for individual patients. As a result, it decreases the need for allogeneic RBC transfusion and hence the associated risks. Current follow-up shows no apparent risk of decreased long-term survival from an oncological perspective. • The authors advocate routine availability of ICS for all major urological oncology cases.

Comparative Study
Laparoscopic bilateral native nephrectomies with simultaneous kidney transplantation.
Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Extirpation of polycystic kidneys for various medical reasons has been performed using many different approaches in attempts to limit morbidity from such a large operation. In indicated patients, it has usually been offered in a staged approach with renal transplantation to avoid graft complications. We published the first case of simultaneous laparoscopic bilateral native nephrectomy with kidney transplant in 2008. The present study shows our continued experience with offering this minimally invasive, single surgery alternative. The results are comparable to a staged laparoscopic approach with significantly shorter total hospital stay and one recovery for the patient and his/her family. ⋯ • In ADPKD, a less invasive laparoscopic approach for native nephrectomies with simultaneous renal transplant offers comparable morbidity without graft compromise and the convenience of one operation and one recovery for the patient.
